New XCAFDoc classes:
- XCAFDoc_AssemblyIterator: iterator in depth along the assembly tree
- XCAFDoc_AssemblyGraph: assembly graph with iterator
- XCAFDoc_AssemblyTool: provides generic methods for traversing assembly tree and graph
A method for re-scaling (sub-)assembly geometry is added to XCAFDoc_Editor.
New DRAW commands:
- XDumpAssemblyTree: iterates through the assembly tree in depth up to the specified level, if any
- XDumpAssemblyGraph: prints assembly graph structure
- XDumpNomenclature: prints number of (sub-)assembly/part instances
- XRescaleGeometry: applies geometrical scale to (sub-)assembly
All uses of "MDTV-Standard" and "MDTV-Design" in tests changed to "BinOcaf", and "MDTV-XCAF" changed to "BinXCAF".
Formats changed: .std to .cbf, .dxc to .dbf.
Test groups renamed accordingly:
xcaf: brep_to_dxc -> brep_to_xbf, igs_to_dxc -> igs_to_xbf, stp_to_dxc -> stp_to_xbf, dxc -> xbf/A1, dxc_add_CL -> xbf_add_CL
xml: ocaf_std -> ocaf_cbf, xcaf_dxc -> xcaf_xbf
