	var $enableLogging = TRUE;				// Boolean: If true, actions are logged to sys_log.
	var $reverseOrder = FALSE;				// Boolean: If true, the datamap array is reversed in the order, which is a nice thing if you're creating a whole new bunch of records.
	var $checkSimilar = TRUE;				// Boolean: If true, only fields which are different from the database values are saved! In fact, if a whole input array is similar, it's not saved then.
	var $stripslashes_values = TRUE;		// Boolean: If true, incoming values in the data-array have their slashes stripped. ALWAYS SET THIS TO ZERO and supply an unescaped data array instead. This switch may totally disappear in future versions of this class!
	var $checkStoredRecords = TRUE;			// Boolean: This will read the record after having updated or inserted it. If anything is not properly submitted an error is written to the log. This feature consumes extra time by selecting records
	var $checkStoredRecords_loose = TRUE;	// Boolean: If set, values '' and 0 will equal each other when the stored records are checked.
	var $deleteTree = FALSE;				// Boolean. If this is set, then a page is deleted by deleting the whole branch under it (user must have deletepermissions to it all). If not set, then the page is deleted ONLY if it has no branch
	var $neverHideAtCopy = FALSE;			// Boolean. If set, then the 'hideAtCopy' flag for tables will be ignored.
	var $dontProcessTransformations = FALSE;	// Boolean: If set, then transformations are NOT performed on the input.
	var $clear_flexFormData_vDEFbase = FALSE;	// Boolean: If set, .vDEFbase values are unset in flexforms.
	var $updateModeL10NdiffData = TRUE;		// Boolean/Mixed: TRUE: (traditional) Updates when record is saved. For flexforms, updates if change is made to the localized value. FALSE: Will not update anything. "FORCE_FFUPD" (string): Like TRUE, but will force update to the FlexForm Field
	var $updateModeL10NdiffDataClear = FALSE;	// Boolean: If true, the translation diff. fields will in fact be reset so that they indicate that all needs to change again! It's meant as the opposite of declaring the record translated.
	var $bypassWorkspaceRestrictions = FALSE;	// Boolean: If true, workspace restrictions are bypassed on edit an create actions (process_datamap()). YOU MUST KNOW what you do if you use this feature!
	var $bypassFileHandling = FALSE;			// Boolean: If true, file handling of attached files (addition, deletion etc) is bypassed - the value is saved straight away. YOU MUST KNOW what you are doing with this feature!

You must set this externally. You must make sure the fields in this array are also found in the table, because it's not checked. All columns can be set by this array!
	var $alternativeFileName = array();		// Array [filename]=alternative_filename: Use this array to force another name onto a file. Eg. if you set ['/tmp/blablabal'] = 'my_file.txt' and '/tmp/blablabal' is set for a certain file-field, then 'my_file.txt' will be used as the name instead.
	var $alternativeFilePath = array();		// Array [filename]=alternative_filepath: Same as alternativeFileName but with relative path to the file
	var $data_disableFields=array();		// If entries are set in this array corresponding to fields for update, they are ignored and thus NOT updated. You could set this array from a series of checkboxes with value=0 and hidden fields before the checkbox with 1. Then an empty checkbox will disable the field.
	var $suggestedInsertUids=array();		// Use this array to validate suggested uids for tables by setting [table]:[uid]. This is a dangerous option since it will force the inserted record to have a certain UID. The value just have to be true, but if you set it to "DELETE" it will make sure any record with that UID will be deleted first (raw delete). The option is used for import of T3D files when synchronizing between two mirrored servers. As a security measure this feature is available only for Admin Users (for now)

						// The only solution I could come up with (except removing support for managing files when autoversioning) was to convert all relative files to absolute names so they are copied again (and existing files deleted). This should keep references intact but means that some files are copied, then deleted after being copied _again_.
						// Actually, the same problem applies to database references in case auto-versioning would include sub-records since in such a case references are remapped - and they would be overridden due to the same principle then.
						// Illustration of the problem comes here:
						// We have a record 123 with a file logo.gif. We open and edit the files header in a workspace. So a new version is automatically made.
						// The versions uid is 456 and the file is copied to "logo_01.gif". But the form data that we sent was based on uid 123 and hence contains the filename "logo.gif" from the original.
						// The file management code below will do two things: First it will blindly accept "logo.gif" as a file attached to the record (thus creating a double reference) and secondly it will find that "logo_01.gif" was not in the incoming filelist and therefore should be deleted.
						// If we prefix the incoming file "logo.gif" with its absolute path it will be seen as a new file added. Thus it will be copied to "logo_02.gif". "logo_01.gif" will still be deleted but since the files are the same the difference is zero - only more processing and file copying for no reason. But it will work.

	 * Reason for copying RTEmagic files: a) if you remove an RTEmagic image from a record it will remove the file - any other record using it will have a lost reference! b) RTEmagic images keeps an original and a copy. The copy always is re-calculated to have the correct physical measures as the HTML tag inserting it defines. This is calculated from the original. Two records using the same image could have difference HTML-width/heights for the image and the copy could only comply with one of them. If you don't want a 1-1 relation you should NOT use RTEmagic files but just insert it as a normal file reference to a file inside fileadmin/ folder
