Concepts

The concepts involved should be documented.

Different adaptive schemes

The globally adaptive schemes could be extended.

Different acceleration schemes

Wynn's epsilon algorithm, while robust, only accelerates linear convergence.

Make acceleration multi-integrand capable

Acceleration can only be used with scalar integrands at the moment.

Extract trait specialisations

Extract trait specialisations into headers, one for each type (carray, array, vector, boost::interval, etc).

Provide trait specialisations for non-built in types

eg boost::interval, NTL, etc
