CrystalTools with orthaNormalize method

[Owen Arnold]

In order to complete #7012. I will need to make some additions to the UnitCell type, however, this close to the 2.6 release, this is not sensible. A better option would be to include a python module in the scripts called something like CrystalTools. We can start this by moving the orthoNormaize methods from the matlab/ALF tools to some new Mantid scripts.

• Create a new module called CrystalTools within scripts
• Create a new method called orthoNormaize, which takes a UB, or OrientedLattice (haven't decided what is best yet), and calculates an orthogonal basis for a*, b*, c*, with x parallel to a*
• Create unit tests to cover the tools

[Owen Arnold]

Invalid. No need to handle orthoNormalize, because the UnitCell type does these orthonormalize procedures already.
