/**
* 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.
