Detailed Description

Performs input/output.

Holds information on input and output files that will need to be accessed throughout the simulation and allows their access via the singleton design pattern.

init()

void Communicator::init	(	double	_tau,
		bool	outputWorldline,
		string	_initName,
		string	_fixedName
	)

Initialize the output files.

Initialize all input/output files.

If we are in the grand-canonical ensemble, then initialize all output files with the form gce-xxx-T-L-mu-tau-ID.dat, whereas if we are in the canonical ensemble we label as ce-xxx-T-N-n-tau-ID.dat.
