A bimap can act as two regular maps, and does so through two special  
public data members.  The "left" member acts like a map<bitset, int,  
BitSetComp>, and the "right" member flips the first two arguments.   
There are also type-aliases defined for each iterator, left or  
right.  There is also a mode that acts like a std::set< std::pair<  
std::bitset< 6 >, int > > >.  Read the docs for the specific names  
and modes.
