This adds a new feature, tracking of mock assignments. You can see when things were assigned and the stacktrace of where it was assigned. This can be found in `MegaMock` objects under the `megamock_attr_assignments` attribute. This is a dictionary where each key is the attribute in question, and the value is a list of `AttributeAssignment` objects.

Support for `wraps` was added. This is for drop-in compatibility with existing Mock logic and makes no improvements. `spy` will be the improved version.

Add `pytest` plugin
