To remove a registered routine, pass in a NULL fptr.
<P>
Users who wish to register new classes for use by a particular PETSc
component (e.g., <A HREF="../SNES/SNES.html#SNES">SNES</A>) should generally call the registration routine
for that particular component (e.g., <A HREF="../SNES/SNESRegister.html#SNESRegister">SNESRegister</A>()) instead of
calling <A HREF="../Sys/PetscFunctionListAdd.html#PetscFunctionListAdd">PetscFunctionListAdd</A>() directly.
