// Note from Rod 2013-01-22:
// This module needs to be refactored to share the same code that is in
// interface/main/calendar/find_appt_popup.php.  It contains an old version
// of that logic and does not support exception dates for repeating events.

// Rod mentioned in the previous comment that the code "does not support exception dates for repeating events".
// This issue no longer exists - epsdky 2019

//continue session
// Will start the (patient) portal OpenEMR session/cookie.
