Error type is difficuit

[ollyde]

I would like if this library follows the rust standard where errors are a type we can manage and handle.

For example

object_to_validate.validate().unwrap_err()

This just returns a default error type with no way to infer what happened.

Since validate returns a Result, what you want is already possible.

I have modified the code in the readme sample to be simpler.
