Summary:
It appears that my initial implementation was not really working when one
starts doing nesting. This diff is fixing this by replacing itertools with
something that is really easy to reason about.

Summary:
This diff is introducing abstractions for parameter sharing for all the
parameters, that are created through new create_param syntax.
Possible use-cases of this parameters sharing:
1. Share params within RNN interface.
2. Some complicated models that might share some of the branches.
3. TODO (next diff): Cross-model parameter sharing.
