Synchronized with HexKit v1.1.

Merged in fixes and changes from HexKit development.

Synchronized with HexKit release.

This release merges in changes made in support of HexKit. Primarily, these are documentation and organizational changes. The only functional change is the addition of the static readonly property HexCoord.origin, which is a shortcut to default(HexCoord) or new HexCoord(0,0).

IsWithinRectangle() refinement.

IsWithinRectangle() no longer relies on simple offset-coordinate bounds checking. The output is now consistent across all permutations, generating one of three row patterns (one symmetrical, two mirrored) as appropriate to the specified corners.
