//! This module is for language specific implementations of the traits in the
//! `parsing` module. These traits are separated out as not all languages
//! have the same features to be extracted. For example,
//! Python has Function names to be extracted, but as its
//! identifiers do not have statically knowable types, it
//! is not Identifiers.
//! C and Java on the other hand have both extractable Functions
//! and Identifiers.

/// Provides traits for parsing different features of source code
