Subject: [PATCH] Use of stable lib feature instead of experimental

The is_multiple_of is a new, experimental feature  introduced to the Rust standard library, but it is not yet stabilized. It requires the nightly compiler to work. Therefore, replacing it with the equivalent modulo operator (%) from stable release.
