/**
 * fetchSysData.php
 *
 * Stub program that's invoked by gaAdmin utility.
 *
 * This program stub connects to the admin mongo resource and pulls all (the whole one record) of system data from
 * the system-data collection.  (There should be either zero (edge case) or one record stored.)
 *
 * The program will store any user-level error messages in an array named $formErrors which will be displayed to the
 * user in the next page load.
 *
 * There is an edge case to be accommodated -- when you request to edit a new Namaste installation and there is no
 * data stored in the system-table.
 *
 * todo: write a program that populates the systemData collection during installation
 *
 * If data exists in the table, it's stored as an associative array in a variable called: $systemData.
 * If data doesn't exist in the table, and if no errors were generated, we're going to assume it's a new (unpopulated)
 * table.  In both of the previous cases, a boolean value: $sysDataLoad is set to true.
