as per Mitko I's implementation:
- There are added a number of patches in binsrc/b3s re: making a fct_dav.vad.
- The code run fine on v6single, next will try vos , probably we would need wrappers for cl_exec & dpipe_define in server code.
- The current vad installs facet browser as it is on lod atm, except its VD is fct to do not break eventual existing sites.
- Also it needs a following indexes as in ~libsrc/Wi/clrdfinx2.sql
- to have a HOWTO and users to make the indexes them-self .
