Description

CopyCommand currently does three things:

• Given a value and a key it overrides an existing key for that value. If no key is given, it associates the value with null
• Given a key, but no value, it removes the key and it's value from the context
• Given a fromKey and a toKey, it copies the value from fromKey to toKey

This should be split up into three distinct commands: OverrideCommand, RemoveCommand and CopyCommand
