[BioC] Elementwise appending of List elements?

[Ryan C. Thompson]

Hi all,

I have 2 CharacterList objects (let's call them A and B) of equal 
length, and I want to append the each element of List A to the 
corresponding one in List B and get the resulting CharacterList. I can 
do this with mendoapply(c, A, B), but this is quite slow. Is there a 
function to do this quickly?
