Tahoe Code SVN development

Beta was removed from the implementation. It should not be implemented when we solve for displacements.

correction for small strain test of element assembly, etc.; it now works correctly for the small strain test

Det*Weight removed from calculating Fd_int in small deformation implementation.

for solid phase,small strain elastic deformation has been implemented. Solver doesn't work correctly.

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.
