abv 42cf5bc1ca 0024002: Overall code and build procedure refactoring -- automatic 
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack

// combination is often encountered in IGES (e.g. Group of Trimmed Surfaces).
// If the compound does contain nested compounds then adds it as an
// assembly.
// The construction happens bottom-up, i.e. the most deep sub-shapes are added
// first.
// If theIsTop is False (in a recursive call) then sub-shapes are added without
// a location. This is to ensure that no extra label in the XDE document is
// created for an instance (as otherwise, XDE will consider it as a free
// shape). Correct location and instance will be created when adding a parent
// compound.
// theMap is used to avoid visiting the same compound.
