Detailed Description

ensemble specific graph update classes, shape-aware acceptance rate calculation and global shape restriction.

To instantiate a canonical network ensemble, using a pair factorized functional weight and sampling only simple graphs do for example

 canonical<link_weight<weight_type::logratio>, shape::simple> E 

Do some updates:

 E.update; E.sweep( some_number );
