- Fix the tests

- Make sure the package actually again gets to the test phase
* the tests are actually failing now

- update to version 2.0.1:
- Added:
- [Registration and discovery] of languages and generators ([#187])
- New textx CLI commands for listing generators and languages
(`list-generators`, `list-languages`) and calling a generator (`generate`) ([#187])
- Meta-models may now [reference other registered meta-models] using the
`reference` statement ([#187])
- Adding examples and documentation related to scope providers (related to
model modification through scope providers) ([#168])
- metamodel export feature for [PlantUML] ([#165])
- `textx_isinstance` from `textx.scoping.tools` made available in `textx`
([#164], [#157])
- CLI extensibility ([#162], [#161])
- An initial version of FAQ page ([#138]). Thanks Aluriak@GitHub
- A version of `calc.py` exercises usage of
`text.scoping.tools.textx_isinstance()` to inspect model objects types
during traversal. ([#136], [#123]). Thanks dkrikun@GitHub
- A version of `calc.py` in expression example that exercises dynamically adding
properties to object classes ([#126]). Thanks dkrikun@GitHub
- python like imports (named import rules, scope providers affected) ([#114])
- Added `STRICTFLOAT` as buildin type to allow to distinguish ints from floats
in `NUMBER`. Fixed docu link ([#98]). Possible **(BIC)**
