Packmask arrays ("-m"), counts arrays ("-c"), and the dropping of union offset arrays are now source-wrappers, rather than being built into the schemas and generators.
0.3.3
Bug-fix for filling data.
0.3.2
__array__` must support Numpy's signature
0.3.1
Primitive schemas now encode their dtype and dims in the array name.
0.2.8
Fix change to make Schemas more lenient about inclusion of repeated objects. (Had to introduce two memos, one is cumulative, the other not.)
0.2.7
More lenient about repeated structures in a Schema: they can repeat, but they can't be nested.
