How to define your simulation (multibunch)

Work in progress!!!

--- To be updated ---

To define a simulation to run with the PyPARIS ring of CPUs, the user needs to write a simulation class. Each CPU will instantiate a separate instance of the class, and use it to preform the simulation according to the paradigm defined here.

PyPARIS will add to the object a member called ring_of_CPUs, which carries the information about the multiprocess structure and allows each process to identify itself.

A prototype simulation class is defined in the following, and examples can be found in the PyPARIS test folders.
