Parameterize CSM scripts

[rehno-lindeque]

Parameterize scripts and models in order to control them using GUI controls.

Some stuff to take note of:

• We should supply default values for all parameters
• How do we differentiate between integer values and floating point values and is it necessary? So far, hopefully not since javascript easily converts between the two... however for the GUI we may want to generate different controls depending on the interval (perhaps add an optional interval for a range type of parameter)
• Generate uniforms in the GLSL compiler to correspond with parameters
• Generate gui controls for CSM parameters (think about how these will look...)

Types of parameters? Ideas so far... (where [interval] is optional, used to restrict to integers but also floating values)

• range(start, end, [interval])
• param([interval])
