Resolves arguments of type Map annotated with @MatrixVariable where the annotation does not specify a name. In other words the purpose of this resolver is to provide access to multiple matrix variables, either all or associated with a specific path variable.

When a name is specified, an argument of type Map is considered to be a single attribute with a Map value, and is resolved by MatrixVariableMethodArgumentResolver instead.
