- Flattened directory structure to /UserObjects/sDNA_GH
- Installation error messages are now helpful to the user.
- Installation now entirely from Grasshopper - searches for sDNA and Python 2.7, and then save an options file from GH using a Config component.
- Updated quantile to isolate spikes of indistinguishable values (in the histogram), and adjust class boundaries.
- Write_Shp will create a .prj file based on an example provided by the user.
- Extra user params on an sDNA component are now joined with semicolons and used for the advanced option (if advanced has not been supplied).
