Added small improvements.

Small improvements in library

I have updated setup.py reqs and library scope. SUITE scope make much more sense for this library.

Fixes #no_issue

Before merge following needs to be applied:

[ ] At least one example testcase added in testcases/ --
[ ] Library Documentation regenerated according to Generate docs
[x] PR entry added in CHANGELOG.md in In progress section
[ ] All new testcases tagged as prerelease along other tags to exclude it from execution until released on PyPI
[ ] Coverage threshold increased in .coveragerc if new coverage is higher than actual, see the lint-and-coverage step in CI
```
fail_under = 67
```
