added simulation reload functionality

Browse source 
tries to reload the current simulation by allocating new available corecomms, and replacing any references to the old ones

warning: custom made simulation configs may not work with this functionality!

this is a convenience method, and needs dynamic corecomms for reloading more than a constant number of times
