Shader Builder / add type checking in expressions parsing
...
All expressions will now be type checked before actually being parsed.

Shader Builder / add utilities for checking an expression type
...
Type checking is done either against a literal value (number, string...)
or against the operator in case of an expression.
Sometimes it is not possible to infer only one type, for example
the value 'transparent' could either be a color or a string. This
is covered by the fact that all operators expect exactly one type
for their arguments.

Literal Style / add support for variables in the style
...
These variables are accessed using the `var` operator, and are meant
to be mutated directly in the style object. When doing so,
the new value will always be used for the render.
This is intended to be used for modifying the style through external
parameters such as an input field, a slider, mouse position etc.

Webgl / add support for a time operator in literal styles
...
This required adding `u_time` as one of the default uniforms provided by the
webgl helper.

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.

Shader builder / add logic for transforming a style into shader params

This was previously handled by the WebGLPointsLayer class, but is now
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.

The WebGLPointsLayer uses this to handle image icons.

and only for symbols.
