Yes, I guess we have to allow word size to be redefined. I just 
wanted fastest version by default w/o possibility to screw up on 
the user side of things.

Also forgot to mention that can pass BitPacked!(ubyte,2) to Trie 
template as value type to use 2 bit per value. Should reduce your 
width table 4-fold. Just saying;)
