Input, a script to capture key and mouse input

[Owenalacaster]

//=====================================================
// Input, a script to capture key and mouse input
//
// This script will catch and store player input
// from the keyboard and mouse in a struct array.
// Keys and buttons are records as bool states,
// while mouse clicks and movement are kept as
// int and fixed values for the UI and World
// respectively.
//
// To get the state of the X key, you would use:
// playerInput.key.state[c_keyX]
// To get the point of the cursor, you could:
// Point(playerInput.mouse.x,playerInput.mouse.y)
//
// The user may configure the DETECT bool
// constants to set which triggers will be
// created on initialization of the script.
//=====================================================
