ENH: improve funcs and opers in Tensor types
- ensures each Tensor-container operates for the following base types:
- floatScalar
- doubleScalar
- complex
- adds/improves test applications for each container and base type:
- constructors
- member functions
- global functions
- global operators
- misc:
- silently removes `invariantIII()` for `tensor2D` and `symmTensor2D`
since the 3rd invariant does not exist for 2x2 matrices
- fixes `invariantII()` algorithm for `tensor2D` and `symmTensor2D`
- adds `Cmpt` multiplication to `Vector2D` and `Vector`
- adds missing access funcs for symmetric containers
- improves func/header documentations

Test-SphericalTensor2D
|
||||
|
||||
Description
|
||||
Tests for \c SphericalTensor2D constructors, member functions and operators
|
||||
using \c floatScalar, \c doubleScalar, and \c complex base types.
|
||||
|
||||
Cross-checks were obtained from 'NumPy 1.15.1' and 'SciPy 1.1.0' if no
|
||||
theoretical cross-check exists (like eigendecomposition relations), and
|
||||
were hard-coded for elementwise comparisons.
|
||||
|
||||
For \c complex base type, the cross-checks do only involve zero imag part.
