Excit Integration: Iterators and Tiling Iterators

• embed excit inside aml (git submodule)
• design a new tiling iterator interface based on it
• validate on old benchmarks (MCHPC19)

Related to #21.
Might be blocked by #51

Integrating Excit

Choice between submodule and external dependency: submodule is easier for development.

Tiling Iterator API

First design choice: tiling iterator object or just a way to retrieve a retrieve a tile using an iterator state as input ?

	object	tiling method
pros	"hide" excit from the user	simple implementation
cons	pretty much need an entire building block with generic API and implementation	excit becomes part of AML API

One point of note: excit would be useful for other parts of AML, in particular topology management.

-> We've settled for an index_byiter for now, but we might need to do both in the end.

Second design choice: do we need to be able to convert two-ways between tile and iterator ?

• it is difficult to recover a tile coordinates from a layout already
• it is not clear we need this functionality: we don't have use-cases at this point

-> Leave it for now.

Integration

We need to port the mchpc19 dgemm to this interface.
