====================================================
This function takes parameters named GeoId, which evoke the Sketcher GeoId and which
indeed are used by the sketcher. However, these indices are just indices of the provided
geometry list. Therefore:
1. The are never negative (no matter if a corresponding Sketcher GeoId is external or not).
2. They do not have reserved indices for axes.
3. Most importantly, not found GeoId1 and GeoId2 are coded as -1, which for the Sketcher has
a well defined meaning (axis), whereas the Sketcher uses Constraint::GeoUndef as undefined or
not present/ not found index, which currently is -2000.
For these reasons, it was judged appropriate to rename the parameters and documentation to
emphasise that this function is unrelated and dettached from any Sketcher knowledge, and that
indices are just normal indices of a vector.
+ some are doxy others are just comment code.
+ some minor whitespace and grammatical tweaks.
+ app/SCL/* typos have also been submitted upstream (https://github.com/stepcode/stepcode/pull/366). So it's ok to merge them in to master.
AttachableObjects are desired in multiple occasions, and the current AttachableObject is not flexible enough to handle all cases. Hence the code is portet to an extension, which gives the needed flexibility.
- remove StdDirection,StdAxis and StdMirrorPlane properties
- support sketch H_Axis, V_Axis, N_axis as valid references in patterns
- polish reference selection gui (unified for standard axes and custom references)
