GGU-SETTLE: "Edit nodes (individually)" menu item

Using this menu item it is possible to retroactively edit individual nodes of the constrained modulus mesh. By double-clicking near a node the following dialog box opens, allowing the coordinates to be edited.

After clicking the "Layer depths" button in the above dialog box or by clicking directly in the constrained modulus profile, the layer depth dialog box opens; it can also be opened via the menu item "Soils/Edit layer depths".
