Modified files: src : Recurrence.cc rr_classifier.cc
Log message: Several improvements to the function `rewrite_non_linear_recurrence()' and `classification_summand()': now the simple case of non-linear recurrence `x(n) = c x(n-1)^a' (with `a' and `c' constants, `a != 1') is recognised. In the aforesaid simple case of non-linear recurrence `Recurrence::compute_non_linear_recurrence()' returns immediately the solution without to build and to solve a linear recurrence.
