Moved generator to project, redesigning the flattening.
Working initial flat version
Added filter and collapse methods and icons
Sync for collaborative work
Fixed folder toggle showing open/closed

If the folder open was false the grid was not taking into account properly that the children should not be shown. Fixed now so proper folder toggling occurs.
