120// local functions

122
123// The follwing function is local rather than a member of CombinatoricList
124// as that would require the file <vector> to be included in
125// CombinatoricList.h, and thus in many other parts of the code. That
126// inclusion can sieverly slow down compliation and also cause many
127// local copies of the code to be generated. It is best to avoid this.
128//
129// Now, you may ask why make this a static function in a class. The simple
130// answer is it works! I tried this as a simple, normal static
131// (i.e. file-scope) function and my compilers barfed. Why do it work
132// in a class? I don't know, but it does so lets just get one with it!
