-This command is used to construct a Generalized :math:`\alpha` integration object. This is an implicit method that like the HHT method allows for high frequency energy dissipation and second order accuracy, i.e. :math:`\Delta t^2`. Depending on choices of input parameters, the method can be unconditionally stable.

     * :math:` \alpha_F` and :math:`\alpha_M` are defined differently that in the paper, we use :math:`\alpha_F = (1-\alpha_f)` and :math:`\alpha_M=(1-\gamma_m)` where :math:`\alpha_f` and :math:`\alpha_m` are those used in the paper.
