changing sign of the force vector

commented out arbitrary prescription of nodal displacements within element
subroutine; there is a problem with the stiffness matrix and/or forcing vector

changing F to F_Transpose in calculating K_dd_G3_5.

Implementation checked for two successive iterations.
correction in jmath temp matrix.

Revision of output data.

Changing the settings of state[k_tied_flag] and changing the check for debugging.

printing results before and after applying BCs in successive iterations. Solver should take into account essential BCs.

Changing the settings of mr_rp_2d.info for debugging

fixed error with voigt notation for tensor multiplication.

log(J) changed to log(fabs(J)) in calculating second piola stress tensor. Solution diverges probably because of BCs.
