   4  * Download documents from OpenEMR to the patient portal in a zip file(get_patient_documents.php)

   6  * This program is used to download patient documents in a zip file in the Patient Portal.
   7  * The original author did not pursue this but I thought it would be a good addition to
   8  * the patient portal
