Is a static instance of a stateful allocator the only way to make the 
BGL graph interface accept it with boost::container_gen, or is the use 
of a stateful allocator with the BGL possible?

The reason this is necessary is that I'd like to wrap an array class 
(which isn't STL compatible) provided by a third party for use with the 
BGL so that I can navigate the array of vertices and edges as modeled by 
the graph it contains. This array class however is useless unless it 
receives a reference to an instance of the stateful allocator upon its' 
construction. Currently I have to hold a BGL graph in memory which 
contains vertex and edge array indices reflecting matching positions in 
instances of the third party array class (one for the vertices, one for 
all the edges). (Unrelatedly but possibly useful to know) Once this 
graph is complete, I need access to the arrays themselves to pass them 
on to other objects that are part of the third party library.

Thanks,
Geoff
