- Retrieves value from $wgRequest->getVal(name, default);

- default= default value to use if argument named arg is not set
- This may eventually be used to fill in a value in other cases, but for now it doesn't.
- index= treats name as an array, and specifies the element to use
- isolate: use extreme isolation to prevent parsing before output
- lcase: convert to lowercase before output
- len= maximum number of characters to include; truncate after nth character
- name= name of variable to retrieve
