    Redefine defmcallback to provide and accept scalars from CL functions · c83788ed
    Liam Healy authored
    New definition for defmcallback will now convert C array pointers
    passed to the function by GSL into individual scalar arguments of the
    CL function, and will take multiple value returns and assign as
    elements of the return C arrays.  Applied to def-ode-functions and the
    van der Pol oscillator example.  Redefined #'maref-function-picker as
    a macro from a function, eliminating the need for an eval-when form.
