Bug 2500 Correcting incorrect splitting of cutter numbers

This patch does two things to improve the call number splitting algorithms:

1. It makes changes to ensure that cutter numbers are split correctly in ddcns

2. It moves custom/fiction/biography call number splitting to a separate algorithm.
    Before they were incorrectly placed in ddcns.

This patch also modifies the call number splitting tests to accept call numbers from the
command line to allow quick testing of any give call number against a particular algorithm.
