HypgFr:

-------------------------------------------------------------------------------
   Computes the value of the ratio of hypergeometric functions

   F(alpha,beta+1;gamma+1,x)
   -------------------------
     F(alpha,beta;gamma,x)

   HypgFr(alpha,0,gamma,x) = HypgF1(alpha,gamma+1,x)

-------------------------------------------------------------------------------
   Form:
   [F, n] = HypgFr( alpha, beta, gamma, x )
   [F, n] = HypgFr( alpha, beta, gamma, x, tol )
   [F, n] = HypgFr( alpha, beta, gamma, x, tol, nMax )
