/**

* Namespace TextInput written by Justin Klein, 2004

*

* This namespace contains 3 functions to allow text input to be gathered in a buffer,

* so that it can be rendered in an OpenGL window.

* void Init() Sets up the buffer

* char* GetTextInput() Polls the keyboard for keypresses, and returns the current

* buffer (a string of the characters seen up to this point)

* void ClearTextInput() Resets the buffer to no contents.

* char* GetCompleteLine() If the last key pressed was "enter" or "return", returns the full text (excluding

* the trailing newline) of the user's input; otherwise returns NULL.

* bool* PollKeyboard() Returns a 256-bool array containing the current state of the keybaord, where

* state[VK_DELETE] is true if delete is pressed down at the time of the call.

* bool* PollSinglePress() Returns a 256-bool array containing the current state of the keybaord, where

* state[VK_DELETE] is true if delete has been pressed (but wasn't pressed before)

* bool isAnyKeyPressed() Returns true iff a key is pressed that was NOT pressed before (new keypresses only)

*

* BUFFER_SIZE This constant can be changed to allow for smaller or larger

* buffers.
