Hello getfem project

I added the HHT transient scheme to GetFEM++.
Could you review devel-tetsuo-hht_method branch and merge?

I used this paper.
HILBER, H. M., HUGHES, T. J. R., AND TAYLOR, R. L. Improved numerical
dissipation for time integration algorithms in structural dynamics.
Earthquake Engineering and Structural Dynamics 5 (1977), 283-292.

I checked that this scheme is equal to Newmark scheme when alpha is 0.

This scheme is added to DIANA and is useful for contact problem.
Thank you for reading.

Best Regard Tetsuo
