Use 0 as \$partid for problems without parts. \$version is optional and returns the \$version-th submission of the student that was graded. If \$version is 0 or ommitted, the latest submission is returned.
+\$encode is also optional and allows the author to explicitly encode the returned string. It's up to the author to take care of properly escaping all characters which might be interpreted by the browser.
+\$cleanupnum is also optional, and supports clean-up of the retrieved submission. It is a reference to a hash, with one or more of the following:
+exponent =$>$ 1,
+comma =$>$ 1,
+letterforzero =$>$ 1,
+spaces =$>$ 1,
