This is an initial draft implementation for modules, that I picked up about a week ago. Hopefully, this will lead to use statements and eventually, a standard library.
Syntax
A module can be defined similarly to Rust:
Any element in a module should be referenced with the module prefix:
Unless imported into scope.
Additionally, pest searches a default location for its standard library, which is added as the
stdmodule.
