myStore: python persistence.

    # control.  So always load from the current version using the default filename.  It also
    # contains the current version number so no need for filename antics.  All results are 
    # kept in the local `res` directory so store functions ultimately load and save the `res`
    # dict.
    # Use as,
    # res = myStore() # instantiate, get latest version
    # r = res.res # shorthand.  Refer to r[] as result dict.
    # r['testValue'] = 1 # set dict value/
    # res.update() # Writes to disk and updates version.

    # del(r); del(res)
    # res = myStore() # instantiate, get latest version and data.
    # r = res.res
    # r['testValue'] # works.
