docs: Handles routing and validation for parsing an error which has been indicated
  to be of type Number. This handler will manufacture a new Error to create
  a stack-trace for submission to the Error API and will attempt to caste the
  given number to a string for submission to the Error API.
  @function handleNumberAsError
  @param {Number} err - the number submitted as content for the error message
  @param {ErrorMessage} errorMessage - the error messag instance to marshall
  error information into.
  @returns {Undefined} - does not return anything
