changes on convergence tolerances of AL and Polarisation, switched back to immediate correction of stress bc but only when last two average stresses are close to each other (cosine decay)

introduced dynamics for high strain rate simulations. so far only works for materials with homogeneous density. the density is read in as an optional argument in the load file using the keyword 'den' or 'density'. if density > 0 then inertial terms are added to the stress equilibrium. an implicit euler time discretisation is used to calculate the inertial terms.
...
dynamic problems are length scale dependent so make sure the geometry size is meaningful (1 m^3 or N m^3 for example is too big for a RVE!).
not specifying a density (density = 0) will perform a quasi static simulation as before.

decoupled compatibility/equilibrium calculation from stress BC correction. needs more iteration for mildly contrasted materials, but there the basic scheme is better suited anyway. but now converges better for highly contrasted VEs

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.
