49.3 Possible improvements to contrib_ode
=========================================

These routines are work in progress.  I still need to:

   * Extend the FACTOR method 'ode1_factor' to work for multiple roots.

   * Extend the FACTOR method 'ode1_factor' to attempt to solve higher
     order factors.  At present it only attemps to solve linear factors.

   * Fix the LAGRANGE routine 'ode1_lagrange' to prefer real roots over
     complex roots.

   * Add additional methods for Riccati equations.

   * Improve the detection of Abel equations of second kind.  The
     exisiting pattern matching is weak.

   * Work on the Lie symmetry group routine 'ode1_lie'.  There are quite
     a few problems with it: some parts are unimplemented; some test
     cases seem to run forever; other test cases crash; yet others
     return very complex "solutions".  I wonder if it really ready for
     release yet.

   * Add more test cases.
