* Context:
* the EquipmentLoanOrReturnDocument document can be accessed by clicking "loan" on the Asset lookup results.
* With this document, a user may decide to lend an asset to someone.
* Therefore, the borrower will want to approve the document confirming that he indeed wants to borrow the item.
*
* Requirement:
* The service will take in a document number as a role qualifier.
* It will retrieve the document given the doc ID, extract out the user ID of the borrower
* (the borrowerUniversalIdentifier property of the document object),
* and return this principal ID as the only role member for a given document.
