+/*
+ * First Attempt at generating the TLC output code from an image.
+ * Run this with "java AnimationCreator"
+ * It will read any image file in the current directory and create an animation for the TLC library.
+ *
+ * Right now this only works with 1 TLC with 16 LEDS connected to it, where
+ * output0 is the bottom and output15 is the top.
+ *
+ * For best results make your files 16 pixels high and as wide as you want.  Each vertical pixel
+ * corresponds to an LED output.
+ *
