cuminc testing for downstream functions

[SHAESEN2]

Testing of estimate_cuminc is now complete, but the downstream functions still need UAT for the new object.

which functions still need testing? I can work on adding them too

Best to check the covr report.

@SHAESEN2 i added a few unit tests in #387 and code coverage is up to 100% now FYI. it's not as full coverage as the tests for estimate_KM(), but it's pretty good!

Not sure if you want to keep this issue open?
