[DISCUSSION] Docstrings in codebase

[valentynbez]

For now, a lot of functions and classes remain without documentation. In order to understand their function, purpose and methods it's necessary to dig through a code of a few separate files.
Example: finding the exact function for calling SNV from BAM files made me go through 5 different files.

Adding verbosity to the code will help understand the internals and decrease the entry level for contributions.

I agree 100%.
