ProcessMeriemsDataset()

This method was written 9th March 2015 to process a dataset of some 1000 x 5 second recordings. The dataset was originally prepared by Meriem for use in her Master's thesis. The data is being processed to produce grayscale spectrogram images for use by Mangalam. She will classify them using a CNN. Note: NO SNR statistics are calculated. All reocrdings must be in single level directory.

Declaration
public static void ProcessMeriemsDataset()
