//  Color notehead plugin version 1.1
//	Noteheads are colored according to pitch, according to the BoomWhackers convention. 
//  Each pitch has a different color. C and C# have a different color. C# and Db have the same color.
//  User can change to color by modifying the colors array. First element is C, second C# etc...
