Add algorithm to index the peaks in a peaks workspace using the UB matrix stored in the sample field of the workspace.

[Dennis Mikkelson]

After determining or modifying the stored UB matrix, the peaks in the peaks workspace need to be indexed.

In [14065]:

Added low-level method IndexingUtils::CalculateMillerIndices()
that will calculate Miller indices for each specified Q
vector. If the indices are not within the specified tolerance
of integer values, then (h,k,l) is set to (0,0,0).

Added method to do a fairly thorough "sanity check" on the UB
matrix to IndexingUtils::CheckUB(). Add code to use CheckUB()
to the FindUB_* and IndexPeaks algorithms, and to the low-level
IndexingUtils code that does most of the work.
Fixed seg fault found by Owen.
