Move sortedXY to Vector.hs, fix shadowing of scanH.
Simplified grahamCHSteps by making use of a more generalized scanH
function.

This is a good guess... the maximum of possible steps shouldn't
be higher than twice the length of the points.

There was also a bug to be fixed when doing this. We missed
an important pattern match case which casued wrong results.

We also slightly changed the behavior of the algorithm and
now split it at 3 elements. It doesn't matter complexity wise
and improves readability a bit.

It was imprecise before and only worked by accident.
'grahamGetCHSteps' is a bit broken for now and caused duplicates.

Fix step depth in grahamGetCHSteps
...
If we have 3 points and pass 1 to 'g' then 2 steps will be computed.
That means we have to substract 2 from the total length in the call
to 'g'.
