#4 Grid/Axis Versatility

[Jess Wright]

It would be nice to give the user (the library user) more control of the axis/grid setup than the simple visibility toggle that is currently available.

This could be accomplished in two ways:

For the most flexibility (harder to use) it could be done via axis/grid being entities that can be manipulated and added/removed just as Polyhedra are.
For ease of use (less flexibility) a set of grid/axis parameters could be exposed like grid size, density, scale etc.
