/**
 * Description:
 * Loads appropriate import file parser and processes the data returned.
 *    Currently supported:
 *      Palmdesktop (dba file)
 *      iCal (ics file)
 *      vCal (vcs file)
 *      Git Log (text file output from 'git log' command)
 *
 *
 * Notes:
 * User defined import routines may be used, see example
 * in the SWITCH statement below.
 *
 * Input parameters:
 *   FileName:    File name specified by user on import.php user's calendar to
 *                import data into, unless single user = Y or Admin,
 *                caluser will equal logged in user.
 *   exc_private: Exclude private records from Palmdesktop import.
 *   overwrite:   Overwrite previous import.
 *
 * Security:
 * TBD
