Inertia element - add output of beta and gamma
The following features have been added/changed:
- In case of "output, always", all the output is written to a separate output file (*.inl) like all other elements too.
- Principal axes are computed in an incremental fashion. So, they will be consistent with structural nodes orientation, unless the compound body has two or three identical principal moments of inertia.
- Output of momentum and momenta moment have been added.
- Private data for momentum and momenta moment have been added.
- Mat3x3::EigSym uses LAPACK's dsyev routine. So, principal moments of inertia will be sorted in ascending order. Otherwise principal moments of inertia and principal axes will have a random order.
