       Re-computes  the slope of the maximum path from _s_t_a_r_t to _e_n_d with tran-
       sitions  _d_i_r on _s_t_a_r_t and _e_n_d, from the  timing  figure  _f_i_g_n_a_m_e,  with
       voltage  _a_l_i_m  and  temperature  _t_e_m_p. _i_n___s_l_o_p_e is applied on _s_t_a_r_t and
       _o_u_t___c_a_p_a is set on _e_n_d. If _t_e_m_p and _a_l_i_m are negative or 0, the  timing
       figure named _f_i_g_n_a_m_e will be used.
         eg.  ttv_ComputeMaxPathSlope(circuit,  _r_e_s_e_t_[_3_],  _i_n_t_e_r_n_a_l_r_e_s_e_t,  _u_d,
       200, 1e-15, 2.5, 70) returns the slope of _i_n_t_e_r_n_a_l_r_e_s_e_t for the maximum
       path between _r_e_s_e_t_[_3_] rising and _i_n_t_e_r_n_a_l_r_e_s_e_t falling with input slope
       of 200ps on _r_e_s_e_t_[_3_] and 1fF on _i_n_t_e_r_n_a_l_r_e_s_e_t when voltage is 2.5V  and
       temperature 70C.
         Returns 0 on failure.
