Rectangles and Documentation

• Added ways to scale rectangles up or down by floats or sizes.
• Added documentation to the less trivial functions.

The sizeable update

• Turns out sizes are just scalars in 2 dimensions, so to speak. So everything can be scaled by a size now.
• All types now have map functions that transform each component in the same way.

Not quite backwards compatible, because I removed vector-vector scaling in the process.

Culling and Expanding

• removed several things that didn't make sense
• added several things that do
• breaking changes from v0.0.0; i'll stop doing those on minor releases past v1.0
