In general, algorithms shouldn't be dealing directly with the ADS,
the Algorithm base class takes care of these interactions.

Factored out common code

The SelectCellOfType and SelectCellWithForm algorithms now actually
re-index the peaks with the new UB matrix, if the Apply parameter is
true.  Previously, a transformation was applied to the previously
calculated hkl values, however, in some cases the transformation
applied was not correct.

 refs #7011

The lattice parameters could be created by constrained optimization or
other not constrained least squares techniques. Currently, only lattice
parameters created via unconstrained least squares are used.

Ideally, constraints will be for conventional cells only, so this method would
not be used except for niggly cells whose orientation matrix is optimized by
unconstrained least squares.

SelectCellOfType and SelectCellWithForm will now calculate(incorrectly?)
lattice parameter errors assuming least squares optimization(which may not be
correct)

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()
