The algorithms: SelectCellOfType(), SelectCellWithForm() and TransformHKL()
now apply a corresponding transformation to previously computed HKLs, rather
than completely reindexing all peaks with the new UB.  When changing to a
larger conventional cell, this typically gets more peaks correctly indexed.
If the previous behaviour is required, the IndexPeaks() algorithm can be
applied separately to the peaks workspace, after running SelectCellOfType(),
SelectCellWithForm() or TransformHKL()
