Refactoring, getting ready for a big push
Adding examples and use cases for storing keys
ID makes more sense because the id could be the /path/to/the/key.file or just about anything that you could use as a unique identifier
Refactored and updated so a key is persisted using the filesystem and can also be loaded from the filesystem
Refactored
Random changes
Added a sign method, moved the encode and decode hex to util class
Updated tests
Added test
Updated autoloader test, was trying to autoload file that is longer used
