Lots of functions not exported from Buffer/HighLevel.hs

[hamishmack]

Functions like atSof do not seem to be exported from HighLevel. Is this intentional?

[Fuuzetsu]

Somewhat recently export lists were added to a bunch of modules and it turned out that many functions are unused or only used within defining module. If you have use for the extra functions, they can be exported without much hassle.

It would probably be good to do a run through of all the functions and decide export or delete.

Would get rid of alot of annoying warnings.

This problem is not specific to Buffer/HighLevel I think.

Leksah was using atSof, readCharB, nextPointB, prevPointB.

@hamishmack I've just exported atSof, but readCharB, nextPointB and prevPointB seem redundant, because we already have readB, leftB and rightB. Is it OK if I delete those three?
