v0.1

First version of forma.

Basic features

• A 'cell' class with normal (integer) vector operations.
• A 'pattern' class which holds a set of cells in a spatial hash table.
• A bunch of pattern primitives, for rasterizing circles, lines and squares.
• A bunch of basic manipulating functions, for shifting, enlarging, reflecting patterns.

A basic but flexible Cellular Automata implementation

• Custom CA neighbourhoods and update rules.
• Synchronous and asynchronous updates.
• CA can be performed in arbitrary domains.

Helpers for generating 'subpatterns'

• Flood-filling to determine contiguous areas (according to custom definitions of contiguous).
• Voronoi tessellation.
• Binary space partitioning.
• Finding the largest contiguous rectangle in a pattern.
• Finding points on the inner/outer surface of patterns.
