       Returns the slope attached to the minimum path from _s_t_a_r_t to  _e_n_d  with
       transitions  _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.
         eg. ttv_GetPathMinSlope(circuit, _r_e_s_e_t_[_3_],  _i_n_t_e_r_n_a_l_r_e_s_e_t,  _u_d,  2.5,
       70)  returns  the  slope  of  _i_n_t_e_r_n_a_l_r_e_s_e_t  for the minimum delay path
       between _r_e_s_e_t_[_3_] rising and _i_n_t_e_r_n_a_l_r_e_s_e_t falling when voltage is  2.5V
       and temperature 70C.
         Returns 0 on failure.
