`hash(alg/tool/data_handle)` are non-deterministic since
Algorithm, Tool and DataHandle use `hash` to construct
their "identity" (which is returned by their `__hash__`).
This makes the iteration order of `set`s of objects
non-deterministic, which can be a problem since, at least currently,
the names of `Algorithm`s depends on instantiation order.

This is fixed here by using deterministic hashing.
