Updated S-K algorithm data calculatons

Files in skalgodata were updated to further analysis.
computeskparams now takes the UZERO file name and
a the name of a file containing SU(2) samples and computes
the parameters w.r.t. those data sets.  randPhaseAmp computes
random SU(2) operators via uniform phase/amp parameter selection.
uniformPhaseAmp computes SU(2) operators by taking uniform spread
out phase/amp params.
v0.9.8 parallelized table search in skalgo

The bottleneck of skalgo is the search through
UZERO for initial approximations. I tried different
serial implementations but the "loop and collect the
min as you go" version seemed to be optimal. Thus,
I tried parcellfun from the parallel package. This
led to some performance gains.  It will currently use
half the available cores.  Further work might be done
to find/compute the optimal chunks per proc for the
parcellfun launch. The current value of 5 was choosen
via trial and error and data collected by proffindclose
found in the skalgodata folder.
Performance improvements to SK compiler

findclosest is not set up for optional usage of the
parallel package.  The dependency between qcs and parallel
will probably be removed and the usage of parallel will be
encouraged. I saw as much as 2x speedup running findclosest
on 4 cores.  The UZERO table now has a third column which
contains the index of the conjugate for the row.  So
UZERO{k,3} is the index of the conjugate for the sequence given
in row k.  All rows are guaranteed to have their conjugate
in the table. Findcloset now returns the index for the approximating
sequence. skalgo returns a vector of indexes.  QIASMsingle/compile
then converts these vectors to sequences. This change got rid of
the computation of conjugate sequences in skalgo. This should result
in some speedup both from reduced computation and memory management.
Bug fix in skalgo

Fixed a bug left from the changeover of skalgo.
bug and performance fixes for skalgo and co.

The @seq/circ2mat was computing the product backward.
So, maths and proper testing 1, me 0.  That's fixed now.
The function to convert UZERO index vector to a cell array
of strings was tweaked to avoid array resize/copy costs.
