- Add another arg to newPage to allow overriding the page number. Want to

Browse Source 
create a single pdf with multiple forms for students, each form should start
  on page 1.
- Add a prevLine() function to go back a line.
- Switch the output mechanism to output to an array (and then print that
  array).  For remote transport to downstream SFIABs, we dont' want to output
  the PDF, we want to bundle up the data and return it via. json.  we do NOT
  want downstream fairs communicating directly with our PDF generator, nor do we
  want users of downstream fairs authenticating themselves, from their home browser, as 
  a fair.  The user talks to their SFIAB, that SFIAB goes through the
  remote.php authentication mechanism, and a PDF gets returned.
