Hi there,

I'm hoping I'm not re-inventing the wheel. So, I was looking for a method to
mask a portion of an alignment, e.g. low quality alignment regions or
duplicated regions. I did not find such a thing in Bioperl, so I added a simple
one in SimpleAlign.pm called mask_columns(). It's almost a copy paste of
slice(), except that I was not sure what the Bio::Seq::Meta sections was used
for, so I removed them.

I will attach a diff file, as well as an example.

(this is my first real patch, be kind!)

Cheers,

--Tristan
