A map can be represented as a tree.  While in C++ the the implementation is
an detail you unlikely need to be concerned about and it doesn't have to be
a tree, but could be a more efficient data structure, in this case a binary
tree will do fine and con always be optimized later.  Even better, there is
be plenty of code out there for binary trees, probably even on your harddisk
:-)
