Initial import of math/p5-Math-Round, needed by upcoming graphics/circos.

Math::Round is a Perl module.  It supplies functions to round numbers,
both positive and negative, in various ways.  This may seem like an
odd thing to write a whole module for, but rounding can sometimes be
a little tricky, so I thought some people might find this useful.
