    The DirectoryScanner will normalize include/exclude paths with the appropriate File.separator, so removing for clarity and to eliminate a bug introduced for Windows.  One file separator instance was used, but would Windows' file separator needs to be be escaped in a Java string, i.e. doubled to '\\'.

    Eliminate truncation of decimal values causing skew toward the minimum value of the range when generating a random long.  Improve test to verify random numbers are being generated as a uniform distribution by:
     1. generate a number of uniform-random longs in a known range
     2. compare average of generated numbers to expected average
     3. verify error around expected average is normally distributed
