!> @brief calculation of stress (P) with time integration based on a residuum in Lp and
!> intermediate acceleration of the Newton-Raphson correction
!> @modified by Satya and achal
!> check for detour i.e. if twinning is possible (we are not going ahead in Lp loop consistency)
!> checking by calling the deltaFp subroutine that should return 4 things
!1) deltaFp= Cij (correspondance matrix) representing twinning shear and reorientation
!2) -(twin volume fraction) for each twin system to make it harder for twinned material point to twin again by any twin system
!3) jump in the last sampled volume fraction
!4) logical true if twinning possible false if not occurring
