[Cuis] Continuations in Cuis

[Ken.Dickey]

Hi all,

Did the trivial port of currentDo: et al from the SeaSide code.

I recommend its non-use unless you have experience with continuations (e.g. in Scheme).  

Continuations are only for 'consenting adults'.  I.e. understanding what is going on is moby complex.  See the test cases.
