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

//parallel to one iso let us translate it parallely in the direction to another
//iso (which is located farther from aC2d). Thus, the requirement for closeness
//to the surface bounds may be avoid.
//For example, instead of Abs(theLoc.X()-uf) <= Tol) ... elseif (...-ul..)...
//the comparison if (Abs(theLoc.X()-uf) <= Abs(theLoc.X()-ul)) .... can be used.
//The reason of this fix #12 is that seam is not sure to lie on the bound :
//if a surface is periodic the whole contour may be shifted (e.g. ProSTEP,
