[ADMB Users] vectoizing pow for random effects

[John Sibert]

An interesting feature of doxygen.

The function prototype
  dvar_vector pow(_CONST dvar_vector&,_CONST dvector& t1);
is declared in fvar.hpp, but the function is not actually defined in any 
source module (that I could find with grep).
The doxygen pages for pow list a number of overloads of pow. Most 
entries note the source file and line number where the function is 
defined, but there is no mention of a source file for  dvar_vector 
pow(_CONST dvar_vector&,_CONST dvector& t1);

A useful feature if you know it is there.
