[Perldl] Google Summer of Code Ideas

My first post.  I'm still learning PDL, excuse me if I suggest
something that is already maturely implemented in PDL!

PDL interfaces to sparse eigensolvers such as ARPACK or BLZPACK would
be really awesome.  All us biophysical folks love diagonalizing huge
sparse matrices.
