Besides being a nice thing to _have_,  I'm not sure if implementing these 
might be fun. But I'm afraid that around  christmas this year I may have
a need for  the 3j symbols.  So I might boostify it if I find helpers to 
discuss the implementation, e.g. should one store dynamically look-up tables 
etc.
