Begin porting implementation from tiny_simgrid
More of the structure of the current implementation
of the UDPOR algorithm was imported into SimGrid
with minor alterations to better fit the EventSet
class paradigm, along with some other cleaning up.
The next phase will be two-fold:
1. Importantly, state management will need to be
added into SimGrid. This shouldn't be too difficult,
assuming that we can follow a similar strategy as
The Pham had in tiny_simgrid of mapping State
objects to state id's and using those ids to later
manipulate the state. In SimGrid, the state will be
be used to manipulate the remote process to which
the Exploration has access, instead of manipulating
what's effectively a dummy object
2. Implementing most of the TODO functions
in EventSet etc. This functionality will come
in future commits.
Eventually, we'll want to make an iterative version
of UDPOR to prevent stack overflows, as it is likely
that the unfoldings of programs of any significant size
can get quite deep. For now, though, this is not
strictly necessary to get a first draft implemented
