[WIP] UT "sectional-solid-horizontal"

[Elvira2227]

Added new unit test "sectional-solid-horizontal" to check #463. Fixes #463 .

Redid analysis as in this issue in usBIM.viewer (on the left side of the screenshot) and OIP (on the right).

The former does not read the deck and railings. OIP reads all the parts, but with wrong orientations and the rails are in incorrect shape.

Work in progress

This definitely looks interesting. I see multiple separate issues that can be addressed:

• handling of I profiles: it seems that the code disregards the bottom/top flange inner point - I assume only a single point is somehow missing
• orientation of beams and deck vs the alignment: are there IfcLinearPlacement and/or IfcAxis2PlacementLinear in the file? If yes - we don't support these yet (fully).
• can you post a screen shot of the whole model from top left?

Note: to screen shot just the active window, use Alt + PrtSc, see https://www.digitalcitizen.life/screenshot-windows/
