AliasAndParameterStringTransformer (Command Framework 0.3.0 Documentation)

Type Parameters:

M - the class of the messages for which this transformer can be triggered
```
public interface AliasAndParameterStringTransformer<M>
```
A transformer that can transform a combination of alias and parameter string to another one. It also gets the message from which the combination was derived for determining the new values.
Possible use-cases for example include:
- fuzzy-searching for mistyped aliases and their automatic correction (this could also be used for just a "did you mean X" response, but for that the command not found events are probably better suited)
- having a command that forwards to one command in one channel but to another command in another channel, like !player that forwards to !mc:player in an MC channel but to !s4:player in an S4 channel
- supporting something like !runas @other-user foo bar baz, where this transformer will transform that to alias foo and parameter string bar baz and then a custom Restriction can check whether the message author has the permissions to use !runas and then for example whether the other-user would have permissions for the foo command and only then allow it to proceed
- forwarding to a !help command if an unknown command was issued
