An array of daughter indices making a geometry path.

Can be used to backup/restore a state. Allocated contiguously in memory.

To setup an object of this type, one should use:

TGeoBranchArray *array = new TGeoBranchArray(level);

array->InitFromNavigator(nav); // To initialize from current navigator state

The navigator can be updated to reflect this path array: array->UpdateNavigator();
