Introducing the capability to restart jobs that crashed in the middle of sims. At the moment, this feature is exclusive for Marc. 

Major changes:

CPFEM.f90 => 
1. Moving the initialization out of CPFEM_general into a separate subroutine, which is directly called by the hypela2 (Beware, the Abaqus version must also be modified in order to adapt with this change).
2. Restore primary state variables in CPFEM_init from binary files when requested (Marc flag: restart read).
3. Writing primary state variables into binary files (Marc flag: restart write).

FEsolving.f90 =>
1. Adding functions to recognize Marc restart flags: read and write and the corresponding restart file (parent job).
2. Change the initial value of cycleCounter = -1 in conjuction with the change made the ping-pong scheme

homogenization_RGC.f90 =>
1. Just syntax polishing.

IO.f90 =>
1. Adding functions/subroutines to open binary files for writing the primary state variables for restart purpose.

mpie_cpfem_marc.f90

1. Modification of the general scheme for collection and calculation in order to accommodate the newly added restart feature.
