54aec05989 multishift conjugate gradient added and a strong test: take a diagonal
but non-identity matrix
l1 0  0  0 ....
0  l2 0  0 ....
0  0  l3 0 ...
.  .   .
.  .   .
.  .   .

And apply the multishift CG to it. Sum the poles and residues.
Insist that this be the same as the exactly taken square root
where l1,l2,l3 >= 0.

It generates automatically the linker flags or complains if not found.

d0e4673a3f Getting closer to having a wilson solver... introducing a first and untested
cut at Conjugate gradient. Also copied in Remez, Zolotarev, Chebyshev from
Mike Clark, Tony Kennedy and my BFM package respectively since we know we will
need these. I wanted the structure of

algorithms/approx
algorithms/iterative

etc.. to start taking shape.
