Query: A Universal Hamilton-Jacobi Theory   In this paper we develop a Hamilton-Jacobi theory in the setting of almost
Poisson manifolds. The theory extends the classical Hamilton-Jacobi theory and
can be also applied to very general situations including nonholonomic
mechanical systems and time dependent systems with external forces.
