  Function to solve the coupled flow equations
  We solve it by using matrix calculations:
  A*v_n = V => v_n = A^-1*V
  First we set up a TMatrixD container to make ROOT
  do the inversions in an efficient way, we multiply the current <<2>> estimates.
  Then we fill new TH2D's if the corrected <<2>>'s (cumuNUA object).

  Parameters:
   cumu: CumuHistos object - uncorrected
   type: Reference ('r') or differential ('d') or ('a' or 'b') for 3 correlator

  Calculates the (n,m)-th element in the NUA matrix: 1 if n == m, otherwise:
               <<cos[(n-m)phi1]>>*<<cos[(n-m)phi2]>> + <<sin[(n-m)phi1]>>*<<sin[(n-m)phi2]>>
    NUA(n,m) = -----------------------------------------------------------------------------
                   1 + <<cos[2nphi1]>>*<<cos[2nphi2]>> + <<sin[2nphi1]>>*<<sin[2nphi2]>>

               <<cos[(n+m)phi1]>>*<<cos[(n+m)phi2]>> + <<sin[(n+m)phi1]>>*<<sin[(n+m)phi2]>>
             + -----------------------------------------------------------------------------
                   1 + <<cos[2nphi1]>>*<<cos[2nphi2]>> + <<sin[2nphi1]>>*<<sin[2nphi2]>>
