Tool to build processes dynamically

[phstratmann]

User story

As a user, I want a generic to create Processes dynamically. In many cases, the details of a Process may depend on calculations performed during code execution. In addition, dynamical Process creation allows for a higher level of abstraction.
At the moment, the Optimization Library already has a feature to dynamically create classes in the SolverProcessBuilder. This feature should be made available as generic tool to all Lava developers.

Conditions of satisfaction

• Users can create a Process dynamically
• Users have a clean interface to set implements_process, required_resources, implements_protocol
• Users can create a PyProcModel dynamically

Acceptance tests

• Replace the dynamical Process creation in the SolverProcessBuilder in lava-optim.

This does seem like a very powerful feature, but it also makes debugging and even understanding the generated process graphs significantly more complicated. I would love to see this infrastructure incorporated into Lava alongside some usability improvements for interacting with, visualizing, and debugging the process and process model graphs.
