Initial check-in for files for enhanced element with linear jump. Still very buggy.

implementation of consolidation formulation verified.

adding two new input parameters for type of analysis(consolidation/dynamic) and type of initial condition(geostatic/disp_vel_press)

adding flags for type of analysis(consolidation/dynamic) and type of initial values(geostatic/disp_vel_press).
there is a problem with trapezoid integrator

trying to write calulated initial values to the output.

calculating initial geostatic condition implemented.:

corrected AddNodalForce. Too many nested loops.

debugging
