[SciPy-Dev] Consensus on the future of integrate.ode

Please, please don't implement anything in the SciPy ODE solvers with Boost.
odeint unless it's a separate interface that requires extreme generality.

Boost.odeint uses Boost.uBLAS for its linear algebra (see
http://headmyshoulder.github.io/odeint-v2/doc/boost_numeric_odeint/concepts/implicit_system.html),
and Boost.uBLAS is slow because it tries to be general (everything is
templated), and it has debugging features added by default.

A lot of users (myself included) don't need that generality, and would
prefer the extra performance that you'd get from a code that can use a
faster dense linear algebra library (like an optimized LAPACK, Eigen,
Elemental, maybe MTL4).
