restructured AL solver to resemble polarization scheme and introduced alpha and beta parameters in numerics to determine what kind of solution you want. alpha = beta = 1 results in the AL scheme. alpha = beta = 2 results in the accelerated scheme. safe values are anything in between. changed the solver to use stress calculations on the campatible field which seems to result in faster convergence.

divergence_correction for basic solver variants has now 3 possibilities:
...
0: uncorrected, slope per sidelength (physical dimension) e = res/dim
1: corrected by sidelength, slope per unitlength e = res/1
2: corrected such that distance between FPs e = 1
alway regarding the medium length of x,y,z direction

introduced option for regridding to numerics.f90, working as follows:
...
first cut back is tried if material point model oder BVP solver does not converge.
If no regridding is enabled after max cut back, in case of non-converged material point the simulation stops and in case of non-converged BVP solver it continues.
set regridMode to 2 to enable regridding if BVP solver OR materialPoint model do not converge,
set regridMode to 1 to enable regridding if materialPoint model do not converge, non-converged BVP solver will be ignored as in the standard case.
For regridding, the load case need to have a restart freq set.
enabled restarting for Basic PETSc variant

Introduced an alternative cutback scheme for the nonlocal model, that allows to keep the results of most of the ips that immediately converged, and only do cutbacks in regions where some ips are in big trouble. Only works for nonlocal model and state integrator 2.

introduced preprocessor identifiers Marc, Abaqus, and Spectral to enable conditional compilation. This allows deleted dummy functions that are used by one solver only.
...
Mainly affected modules are IO and mesh. Most of the changes in mesh result from reordering the functions when grouping them depending on their solver.
Further advantage is that FE solver do not need FFTW and kdtree2 anymore. The include files for these two libraries moved to DAMASKROO/lib now as I figured out how to use a include path in the Makefile.
Put all the files I got when testing compilation with abaqus in a folder which to become the abaqus compilation test.
