Single Classification wrapper function

[jatkinson1000]

Currently classifications are called depending on the type of classification required.

Consider a single generic wrapper function that can be called that then recursively calls the existing functions.

All the pylint errors in #25 are hinting that the classifications code smells a bit.
Addressing this with a refactor might help towards reducing some of the pylint issues.

Think this can probably be closed now, #42 was implemented a while ago and things have been restructured much more since via #78
