Simplify a fraction using a simple continued fraction decomposition.
The idea here is to convert fractions such as 333333/10000000 to 1/30
using 32 bit arithmetic only. The algorithm is not perfect and relies
upon two arbitrary parameters to remove non-significative terms from
the simple continued fraction decomposition. Using 8 and 333 for
n_terms and threshold respectively seems to give nice results.</doc>
