Use hashing system (from PyWIT) to avoid recomputing over and over IW2D calculations
The hashing system already provided in PyWIT for IW2D calculations (see pywit.interface.py) is not used at this stage. This hashing system would avoid recomputing all the time the same calculations, and which is inefficient and also possibly increases the number of files in the local file system, simply by checking if the exact same computation was already done (checking the ~/pywit/IW2D/projects/).
The caveat is that right now, HTCondor submission is not implemented in PyWIT yet. Still, the hashing could be used before launching to check if the calculation was already done.
