RE 7011 Fixes select cell bug

The SelectCellOfType and SelectCellWithForm algorithms now actually
re-index the peaks with the new UB matrix, if the Apply parameter is

calculated hkl values, however, in some cases the transformation
applied was not correct.

found you just get the regular unparsed latex in your help.
