This will provide a much more constant block time.		* '''SampleBlockSize:''' Neuralynx has a set packet of data acquisition of 512 points.

			*There is a 2MB memory leak every time there is a new configuration of the system (press of the SetConfig button on the operator module). That means that the module will allow a number of reconfigurations before it runs out of memory.
			*The module checks for the right timing of the Neuralynx provided timestamps in every package it acquires. If there is a discrepancy in these timings the module will stop (thus ending any running experiment) notifying the user of the problem. This is by design but will probably be removed in newer versions because Neuralynx seems to be providing such discrepancies more often than was originally expected.
