OpenGL view for iOS application.

EAGLView class provides OpenGL ES API. t includes usages of Vertex Buffer Objects (VBOs), Vertex Array Objects (VAOs), Framebuffer Objects (FBO), and GLSL Program Objects. It creates a VAO and VBOs from model data loaded in. It then creates a texture for the model from image data and GLSL shaders from source also loaded in. Finally, it creates an FBO and texture to render a reflection of the model. It uses an environment mapping GLSL program to apply the reflection texture to a plane.
