ShaderBuilder / refactoring to use an actual builder pattern
...
There is now a ShaderBuilder class with chainable methods
to specify more easily the contents of the final shaders.
This is to avoid passing around large objects to different functions,
and allow for a richer API.
The documentation has also been corrected and clarified.

externalized and tested.

Shader builder / add basic expression parsing
...
Only a handful of expressions for now, very loosely based on the
mapbox style spec. Also only work on numerical values.

Webgl shader builder / expanded functionality
...
Now takes in a custom object with attributes, uniforms etc.
The WebGLPointsLayer uses this to handle image icons.

Webgl / add a very simple vertex shader builder utility
...
This only allows including hardcoded values in the shader,
and only for symbols.
