    bvds committed May 24, 2011
    and some unused cruft removed.  Change uffi -> cffi,
    removed unused references to error handler and student profile
    file, add forward compatibility for newer problem files
    (but not pointers).

  1. Remove unused files SLog2English.cl StudentFile.cl

    bvds committed Apr 27, 2009
    StudentFile was some attempt at making a model of the student
    and SLog2English.cl turned a log file into an English-language
    conversation.  Could also be removed from Andes2.

    bvds committed with unknown Mar 14, 2009
    (cherry picked from commit de1cf3d)

    by projections and write-mag-torque.  (Following what was done
    with dipole torque.)
    (cherry picked from commit c54726d)
  9. test for nonzero when getting (shape ...) keywords

    bvds committed with unknown Mar 11, 2009
    (cherry picked from commit 921ce82)
  10. add axis to ang-momentum psm & fix typo

    bvds committed with unknown Mar 11, 2009
    (cherry picked from commit 7eb14fd)
  11. Add axis to moment-of-inertia. This forces some other modifications:

    bvds committed with unknown Mar 11, 2009
      The axis choices are given by the positions list, need to modify problems
      Change inheritance and symbol name of moment-of-inertia
      Modify wrong body error handler (need check for wrong axis)
      Add axis slot to ang-momentum PSM; needs (motion body rotating ...) to apply.
      Add :center and :end to various (shape ...) assertions.
      Add axis slot to compound moment-of-inertia.
      Energy rules use (motion body rotation ...); use this to get axis.
        (no slot for axis in the rule itself, may want to add keyword pair
         to make optional slot like we do in NSL)
    (cherry picked from commit d70134b)
  12. Improve error propogation in checksol and eqnumsimp:

    bvds committed with unknown Mar 14, 2009
    If sqrt of negative is less than error, set result to zero.
    If error has already been computed, don't override value.
    (cherry picked from commit a7358f7)
  13. remove unused argument to polysolve

    bvds committed Mar 6, 2009
    relative-position-displacement.  Unfortunately, this didn't seem
    to help dt6a much.
    (cherry picked from commit 72db95f)
  3. Assume positions are always continuous: always use

    bvds committed Mar 6, 2009
    closed intervals when checking for conditions on
    relative-position.

  1. Switch from using :user package to :cl-user, fitting ANSI common

    bvds committed with unknown Feb 9, 2009
    lisp practice.  It may be that old versions of Allegro common lisp
    required :user, but this change should be OK
  2. missing dependency: Knowledge depends on Algebra
