::Version 1.3.9 --Current version!
+Added config option 'colorLimit', which simulates being incapable of rendering certain colors. (2=colors,1=grayscale,0=monochrome)
+Added a means of pathmaking, but it doesn't do anything yet (press space, move, press space)
+Added a new mapColor for the background color of the inside of the minimap
*Added a main config path (.map) where everything is stored. FINALLY.
*Made the mapColors config option more readable
*Fixed the monochrome title screen displaying a gray background for the startup text
*Updated help screen text
*Cleaned up the update code a bit
*Made scaleFactor increase/decrease by 0.1, rather than multiply/divide by 1.1.

::Version 1.3.8
+Added a very basic chat function to main screen by pressing T. Messages cannot be too long, as of yet.
+Added config option 'doFlash', which enables the screen flash effect. Default is false.
*Changed config option 'mapProtocol' to number instead of string.
*Fixed the poorly handled usage of seeking other Map clients (changed from changing rednet channel to using modem API)
*Removed most red herrings

::Version 1.3.7
+Allows 'Map' clients to see other clients around them on the screen! Can be disabled.
+Added config option "broadcastData" to toggle whether you want your coordinates and whatnot broadcasted.
+Added config option "networkName" to identify yourself to other 'Map' clients
+Added config option "mapProtocol" which is the rednet protocol used to broadcast/receive coordinates and stuff.
+Added settings options "Inspect waypoint", which lists X, Y, Z, and other data about a waypoint/player blip.
*Fixed bug where if a turtle turns for the first time, it errors.

::Version 1.3.6
+Made a prompt to enter coordinates in spoofMode, so that turtles can go to waypoints w/o GPS. Does not work on PDAs.
*Fixed the loadstring version so it works with arguments.

::Version 1.3.5
+Replaced a single waypoint file with a waypoint folder, where multiple waypoint files can be placed and used.
+Added the ability to click on commands while on the main minimap screen and the options menu.
+Added the ability to change the scaleFactor by putting your mouse cursor on the "Scale: " and scrolling.
+Added animation on main minimap screen that spins. Each time it spins, a gps request returns. If red (or white), then a GPS connection failed. If a gps request succeeds, then it turns green (or lightGray/black)
*You can only delete or rename waypoints that are located in the file called '/.waypoints/waypoints'.
*Fixed bug where turtles, when being sent to a point and lose GPS connection, stop moving and error.
*Made Map default to turtleMode = true when first ran on a turtle.
*Created and fixed bug where the third waypoint you create isn't put in the waypoint file.

::Version 1.3.4
-Removed youChar config option, because I should've earlier
+Added the ability to have colored waypoints, with colored offscreen arrows!
+Added error handling system (via pcall())
+Added title screen for gray/adv/norm computers, and added a config option to disable it (is disabled by default)
*Fixed bug where, when a point goes over the border, it doesn't have a white background.
+Added mapColors config option, to set the color palate of the program.
+Added directionSensitivity config option, to determine how much you need to move for the direction indicator to change.
+Added monitorTextScale config option, to determine monitor text size when using on a monitor (but why would you?)
*Replaced 'mon' argument with 'fast' argument. term.redirect(term.native()) is now disabled until 'fast' argument is given.
*Fixed very minor flickering thing when pressing 'L' on main screen.

::Version 1.3.3
*Flipped X for the map to make sense. I wonder why I never did this before. Turtles defaultly turn the right way now. (yaaay!)
*Config option 'keyAgoesRight' is no longer needed, but it hasn't been removed just in case someone wants to use it.
*Fixed bug where, in the options menu, if you press PRINTSCREEN, then it errors.

::Version 1.3.2:: (cannot be downloaded, replaced with 1.3.3)
+Improved non-advanced computer greatly, preparing for the latest CC release with gray in normal computers. Keeps support for 1.6 normal computers.

::Version 1.3.1:: (cannot be downloaded, replaced with 1.3.3)
+Added turtle support, allowing turtles to be controlled through WASD
+Allows turtles to be sent to either a set of coordinates or a waypoint, by name
+Added turtleMode config option to go with turtle support
+Added keyAgoesRight config option to reverse left/right controls for turtle support, as turning left on the map turns the turtle right
*Fixed some bugs
*1.3.1 can be updated to 1.3.2 with 'map update'

::Version 1.3::
+Added a more compact options screen to help with accidental keypresses
+Added a Rename function to rename existing waypoints
*Fixed bugs
*Helped with small flickering issues

::Version 1.2.4::
+Added better support for non-advanced computers
+Optimizations
+Added other misc features I forgot about but ARE important
+Added autoUpdate config option to automatically update to current version of your number. Doesn't update the version number
+Added 'mon' argument to disable term.redirect(term.native())
*Fixed lots of bugs
*Optimized the code for much greater speed and less flickering

::Version 1.2.1::
+Added scale factor indicator to screen
+Added ability to change scale factor with numpad +/-
*Fixed tons of flickering issues
*Increased speed with term.redirect(term.native())
*Changed config format to make much more sense

::Version 1.1::
+Now works as planned!
+Added advanced computer support
+Added all shown features

::Version 1.0:: --Cannot be downloaded (for good reason)
+First release as a test
-Doesn't allow saving waypoints automatically
-Most features don't work actually

*There is now a 0.4 second delay between getting coordinates (originally 0 sec.), to reduce rednet spam.
+Color support, and nonadvanced support!
+The ability to set and delete waypoints without going in the program (default list at "/.waypoints")
+Config file for some key variables (default list at "/.map_conf")
+Labels of waypoints on the map show up with their names
+The ability to set the scale factor of the map, allowing you to see a much greater area, to help with small maps
+Improved the direction sensor greatly
+No longer errors when disconnected from GPS server. After an 8 sec. timeout, screen turns red/inverts colors.
+Added visible exit option; the keybinding did exist before, but now it is labeled.

itemX - The X position of any particular waypoint on the map ON THE SCREEN.
itemZ - The Y position of any particular waypoint on the map ON THE SCREEN, so higher points have a lower Y.
corner1 - A table, the first item is the X of the topleft corner of the border, the second the Y.
corner2 - A table, same as corner1 except for the bottomright corner of the border.
