Drop function description was moved up adjacent to the other
functions to provide better document flow making this section
redundant, hence its removal.
The available_classes function is using Subspace.unpack to
obtain the tuple, not fdb.tuple so update the description to
reflect this.
The limited seat tutorial section was missing the code and
text describing the update of the drop function.
Modified all class scheduling documentation pages removing mentioning of UI and updating wording within sections of Done and Are We Done? to be clearer.
Update configuration options within Command Line Interface documentation
Updated language describing Causal Riskiness within Command Line Interface documentation
Removed personal username from Ruby class scheduling documentation file
