+//  This is Jeff LaMarche's GLProgram OpenGL shader wrapper class from his OpenGL ES 2.0 book.
+//  A description of this can be found at his page on the topic:
+//  http://iphonedevelopment.blogspot.com/2010/11/opengl-es-20-for-ios-chapter-4.html
+//  I've extended this to be able to take programs as NSStrings in addition to files, for baked-in shaders
