+ * POST method Roo/TABLENAME
+ * -- creates, updates, or deletes data.
+ *
+ * INSERT
+ * if the primary key is empty, this happens
+ * will automatically set these to current date and authUser->id
+ * created, created_by, created_dt
+ * updated, update_by, updated_dt
+ * modified, modified_by, modified_dt
+ *
+ * will return a GET request SINGLE SELECT (and accepts same)
+ *
+ * DELETE
+ * _delete=1,2,3 delete a set of data.
+ * UPDATE
+ * if the primary key value is set, then update occurs.
+ * will automatically set these to current date and authUser->id
+ * updated, update_by, updated_dt
+ * modified, modified_by, modified_dt
+ *
+ *
+ * Params:
+ * _delete=1,2,3 causes a delete to occur.
+ * _ids=1,2,3,4 causes update to occur on all primary ids.
+ *
+ * RETURNS
+ * = same as single SELECT GET request..
+ *
+ *
+ *
+ * DEBUGGING
+ * _debug=1 forces debug
+ * _get=1 - causes a get request to occur when doing a POST..
+ *
+ *
+ * CALLS
+ * these methods on dataobjects if they exist
+ *
+ * checkPerm('E' / 'D' , $authuser)
+ * - can we list the stuff
+ * - return false to disallow...
+
+ * toRooSingleArray($authUser, $request) : array
+ * - called on single fetch only, add or maniuplate returned array data.
+ * toRooArray($request) : array
+ * - Called if toSingleArray does not exist.
+ * - if you need to return different data than toArray..
+ *
+ * toEventString()
+ * (for logging - this is generically prefixed to all database operations.)
+ *
+ *
+ * onUpload($roo)
+ * called when $_FILES is not empty
+ *
+ *
+ * setFromRoo($ar, $roo)
+ * - alternative to setFrom() which is called if this method does not exist
+ * - values from post (deal with dates etc.) - return true|error string.
+ * - call $roo->jerr() on failure...
+ *
+ * CALLS BEFORE change occurs:
+ *
+ * beforeDelete($dependants_array, $roo, $request)
+ * Argument is an array of un-find/fetched dependant items.
+ * - jerr() will stop insert.. (Prefered)
+ * - return false for fail and set DO->err;
+ *
+ * beforeUpdate($old, $request,$roo)
+ * - after update - jerr() will stop insert..
+ * beforeInsert($request,$roo)
+ * - before insert - jerr() will stop insert..
+ *
+ *
+ * CALLS AFTER change occured
+ *
+ * onUpdate($old, $request,$roo)
+ * - after update // return value ignored
+ *
+ * onInsert($request,$roo)
+ * - after insert
+ *
+ * onDelete($request, $roo) - after delete
