added new math function "math_deviatoric33" which returns the deviatoric part of a 3x3 tensor
...
renamed some math functions, so that we have a universal naming scheme: for matrix multiplications use an "x" (e.g. math_mul33x3); don't use the "x" to describe the shape of the tensor that the function is applied to (e.g. math_invert33 instead of math_invert3x3)

c35ea33f8e
did a lot of polishing:
...
- removed unnecessary "return" before end of subroutine or function:
- changed undetermined array length (:) to (1:3)
To prevent problems with some code analysing tools:
- "3D oneliner loops" (with ";) only for "do" and "enddo" at the same time
- removed line continuation in OMP statements
made the makefile more flexible, removed heap-arrays switch
