 Computational Design!
 
 Title: Handwriting Font App
 Imagined, Designed, and Programmed by: Kevin Hou
 Date: October 30, 2014
 
 Description: This app allows you to input your handwriting and type in it. It returns
 a pdf vector file that you can then print on the watercolor bot. There is a typing interface
 built into the app.
 
 Sources of ideas and inspiration:
 * Similar idea to what was seen in Her: http://en.wikipedia.org/wiki/Her_(film)
 * Microsoft office word typing interface
 
 Includes code from:
 * Adding sliders and buttons for control P5 using the format from the PomPom maker
 
 Added More Code on October 23
 *Apostrophe
