Geometry renderer

[nsdrozario]

Create a renderer using HTML5 Canvas and JavaScript that can create diagrams of geometry problems and formulate a method of input for this renderer and a theoretical data structure to represent input.

UPDATE: Prototypes created.

Key points of architecture:

• has global memory; all information created pertaining to the renderer instance is here
• Each kind of renderable object has a label object that can be attached to it (label class is not yet prototyped)
• Certain settings can change what renders
• Rendering happens in a loop (while loop is wrong approach; it is simply a placeholder for now)

See engine/geo_renderer/main.js for more details.

@shuklanishchal @LampyDaSavage Please implement the commented features within main.js labled IMPLEMENT.
