Print out new lattice constants after TransformHKL

[Peter Peterson]

Just so people have confirmation of what they transformed to. The format should be similar to FindUBUsingFFT.

Re #7846. Adding operator<< to UnitCell.

This is being done to centralize the code for printing out lattice constants and their uncertainties.

Re #7846. Using new ostream operator in UnitCell.

Refactored some bits of code to be using c++ formating rather than sprintf. Also moved things from the header to the implementation.

Re #7846. Printing out transformed lattice constants.

Also moved some implementation from the header files.

This is on ​feature/7846_print_lattice.

To test: Run the "SCD Event Reduction" interface through the point of "Change HKL." You should see the lattice constants printed just before a copy sample in the Results Log.

Turns out I haven't a clue how to drive the SCD interface. However, a couple of things from looking at the code:

• How about quickly writing a unit test for the new stream operator
• The test for showUncertainties around lines 709-721 of UnitCell.cpp is strange code - why not just use one 'if' and a bunch of 'or's?

For some reason the ​last commit didn't get added to the ticket.
