Jacques Pienaar 9d4bb57189 Start a testing pass for EDSC lowering.
This is mostly plumbing to start allowing testing EDSC lowering. Prototype specifying reference implementation using verbose format without any generation/binding support. Add test pass that dumps the constructed EDSC (of which there can only be one). The idea is to enable iterating from multiple sides, this is wrong on many dimensions at the moment.
