      public static double[] map_count_idc(MatrixCell MAP, double[] t)
      Index of dispersion for counts (IDC) of a MAP at a set of time points. The IDC of the counting process A(t) associated to the MAP is I_a(t) = Var(A(t)) / E[A(t)], t > 0, i.e. the scaled variance-time curve. It interpolates between I_a(0+) = SCV of the interarrival time (renewal MAP) and the asymptotic value I_a(Inf) = map_idc(MAP). Reference: W. Whitt and W. You, "A Robust Queueing Network Analyzer Based on Indices of Dispersion", eq. (1).
      Parameters:
      MAP - the Markovian Arrival Process stored in a MatrixCell
      t - array of interval lengths (t > 0)
      Returns:
      array of IDC values, one per element of t
