/**
 * This class allows you to load a theme from a file.
 * It uses the standard Java Properties file format.
 * To create a theme you provide a text file which contains
 * tags corresponding to colors of the theme along with a value
 * for that color.  For example:
 *
 * name=My Ugly Theme
 * primary1=255,0,0
 * primary2=0,255,0
 * primary3=0,0,255
 *
 * This class only loads colors from the properties file,
 * but it could easily be extended to load fonts -  or even icons.
