Longtables

[Dominique]

Thanks for this very useful package!

I added the following to my local clone, which helps me output longtables:

Here's an example use:

latex_tabular("/tmp/table.tx",
              LongTable("rrr", ["alpha", "beta", "gamma"]),  # <- give header here
              [rand(300,3), Rule(:h)])

The main LaTeX document should \usepackage{longtable}.

In longtables, the table header is typically repeated, so I made it part of the LongTable struct. That's a bit different from the standard tabular you implemented. Do this seem acceptable? If so I'm happy to send a pull request.

Yes, a PR would be very nice.

See #5.
