0.2.0

0.2.0

New features:

• Added ScalarField, a 2-dimensional field of scalar values, typically built
  from patterns or noise functions, and buildPlaneMap, a utility function to
  build a flat plane from a ScalarField, useful for terrain generation.

Breaking changes:

• Added <Plattern>.get2df, as an alternative to get2d that takes floating
  point coordinates, which is required for some use cases such the aformentioned
  buildPlaneMap. get2d still exists and is recommended for integer
  coordinates, and is automatically converted to get2df when needed.

Bug fixes:

• Fixed a variety of small math bugs that are hard to describe in detail.
