Fixed issues in schemagenerator.py:
* Multipatch FC domains (they are now always global)
* Validate more inputs to keep some errors from popping up
* Automatic parameter filling from the config files, so that profiling/extending the 3DCIM schema doesn’t require any programming anymore
Fixed three more issues on schemagenerator.py:
1. Autoselection of applicable domains for the activated Feature classes and Tables
2. Tool doesn't try to recreate Domains already in the FGDB
3. Tool wouldn't work when creating WGS 1984 Multipatch Feature classes
