In order to perform certain operations (start/stop/step), meta_range_t objects must be "monotonic", meaning that the subranges composing it are sorted and non-overlapping. This commit creates a method which takes a non-monotonic meta_range_t containing no non-continuous subranges and converts it into a monotonic meta_range_t.
