-Pitch is implemented
-Deleting selection is implemented
-Fixed several bugs related to the highlighting of the window
-Fixed bugs involving space bar triggering controls
-Fixed bugs with lower HZ samples crashing SSRC (small files)
-Implemented Cut, Copy, Paste, Trim, Select All, Delete

NOTES:
-Zoom function doesn’t work with editing the wave file yet (it acts as if you’re zoomed all the way out).
-You can either right click on the wave display or use shortcuts to use the editor functionality.
-CTRL+V = paste, CTRL+C = copy, CTRL+X = cut, CTRL+T = trim, CTRL+Z = revert, CTRL+A = select all
-“quality” Pitch change right now is a bit mediocre quality-wise.  I might just have lots of copies of each .wav file in memory for small files.
-To use copy, cut, delete, or trim you must have something selected (by dragging the mouse and making a rectangle).  To paste something, you need to click once (without dragging) and a single white line will show up- this is where the info will be pasted.
