parseargumentsrs

Easy way to deal with parsing commandline arguments

Crate on crates.io. Documentation on docs.rs or by running cargo doc --open.

TODO

• the key nor the value can have any spaces because of the nature of std::env::args. I will try to fix it at some point.
• ~~the hashmap function clones strings which could be more efficient - maybe with string slices~~ the function would own whatever std::env::Args returns, so using an &str, or even a &'static str would result in a dangling pointer. Afaik, using string slices wouldn't be possible in rust.
