## [2.0.0] - 2021-??-??
## Added
- `CObs` class added which can handle complex valued observables
- Matrix to matrix operations like the matrix inverse now also work for complex matrices and matrices containing entries that are not `Obs` but `float` or `int`
- `Obs` objects now have methods `is_zero` and `is_zero_within_error`
## [1.1.0] - 2021-10-11
### Added
- `Corr` class added
