# tetra-lib

> **Warning** 

> This library is implemented for research purposes only! It *intentionally* doesn't verify some parameters 

> for validity. In real world all parameters MUST be properly verified.

> 

> Furthermore, this implementation doesn't hide internal context fields, because they are used in analysis.
