These are queried continuously by the owner tree view (on Customer/Vendor/Employee
Overview pages) and recalculating them is an expensive operation.
The cache will be invalidated each time a lot reated to the owner
changes (modify or delete). The net effect is a huge responsiveness

It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
