Make SingleValueArgumentList show the valid values in the error message instead of just saying "Invalid value: x".

The representation of ArgumentGroups should not show if they have no description set and the representation of the inner arguments did not return any text.

Currently, the way errors are formatted using ErrorFormatter is rather limiting. For the parser is fine, but the tokenizer should work with characters, and not tokens (because tokenization hasn't finished when the tokenizer throws errors)

There are still some components without proper JavaDocs comments written.

Provide an easier way to see if, once parsed, a Command was used or not.

When defining an argument, you are always forced to specify the type. However, in some cases where simple types are used (such as IntegerArgumentType or StringArgumentType), these types can be perfectly inferred from field types of CommandTemplate classes.

For example, this should be legal:

@Command.Define
class MyProgram {
	@Argument.Define
	public String name; // ArgumentType will be StringArgumentType
}

Note that this will only work for types that are not wrapped inside Optional. (We can't know generic types at runtime)
