  Description     : utility functions to deal with Library-of-Congress call numbers

Library::CallNumber::LC is mostly designed to do call number normalization,
with the following goals: The normalized call numbers are comparable with each
other, for proper sorting The normalized call number is a short as possible, so
left-anchored wildcard searches are possible (e.g., searching on "A11*" should
give you all the A11 call numbers) A range defined by start_of_range and
end_of_range should be correct, assuming that the string given for the end of
the range is, in fact, a left prefix.

That last point needs some explanation. The idea is that if someone gives a
range of, say, A-AZ, what they really mean is A - AZ9999.99. The end_of_range
method pads the given call number out to three cutters if need be. There is no
attempt to make end_of_range normalization correspond to anything in real life.
