Get Methods

=== Description ====
Dispalys the functions of a periperal

Example: Monitor, Turtle, Printer...


==== Installation and Use ====
Pastebin Code: sKLqTGrM

To download a file from pastebin:
pastebin get <code> <name>

Place computer next to the block you want the methods of
Run the program with the side of the peripheral as an argument

This displays the functions of
a peripheral using peirpheral.getMethods(side)


==== Update History ====
The pastebin will always have the most recent version

|1.1|  <-- This program
  -You can now scroll through the pages with the arrow keys
  -You can use it on the regular (non color) computer now
  -Cleaned up code
|1.0|
  -Release
