IFC4 export

The following changes have been made in the IFC4 export of rebar sets:

• When individual rebar set rebar objects were exported (XS_EXPORT_IFC_REBARSET_INDIVIDUAL_REBARS=TRUE), the rebar set was exported together with the individual rebar objects. This appeared as if one extra rebar object was included in the export. This issue has now been fixed, and only the individual rebars are exported.
• When individual rebar set rebar objects are not exported (XS_EXPORT_IFC_REBARSET_INDIVIDUAL_REBARS=FALSE), the rebar set groups are always exported with cast units. Earlier, the rebar set itself was exported instead of the rebar set groups.
• For pour export, where pour units are exported with their rebar objects, nothing has changed, which means that individual rebar objects are always exported, regardless of the value of XS_EXPORT_IFC_REBARSET_INDIVIDUAL_REBARS. 

The illustration below explains the export logic:
