+     * validateMeta() -- public method
+     *
+     * This method requires one input parameter:
+     *
+     * $_meta -- a key-value paired array containing the current meta data payload
+     *
+     * first we validate the input parameter to ensure we're working with valid data object.  If not, we're going to
+     * immediately return a false value and set the gacMetrics property (stopProcessing) to true.  This allows us
+     * to signal the gacFactory class that a processing error had occurred.
+     *
+     * Otherwise, spin through the meta data that was passed to the method and compare each key in the array to the
+     * list of "authorized" keys defined for the current class.  If a key does not exist in the authoritative index,
+     * then remove that key from the input-meta data and record the event in the log file and in the gacFactory
+     * class eventMessages property.
+     *
+     * Method returns a boolean value that indicates if meta data was validated.
+     *
+     * Since the meta data array is passed as a call-by-reference variable, dropped fields will propagate back to the
+     * calling client.  A list of dropped fields, if any, will be stored in the eventMessages container.
