50 /**
51  * This class allows you to load a theme from a file.
52  * It uses the standard Java Properties file format.
53  * To create a theme you provide a text file which contains
54  * tags corresponding to colors of the theme along with a value
55  * for that color. For example:
56  *
57  * name=My Ugly Theme
58  * primary1=255,0,0
59  * primary2=0,255,0
60  * primary3=0,0,255
61  *
62  * This class only loads colors from the properties file,
63  * but it could easily be extended to load fonts - or even icons.
