New-style measurements are coming to the GUI soon !
- moved measurement operations from gui_tools.c to new file gui_meas.c - added support for creating new-style measurements through the GUI - the offset is optional in new-style expressions git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5407 99fdad57-331a-0410-800a-d7fa5415bdb3
