description:
ODE:

Implemented optional experimental fixed-point stabilization for the
mono-adaptive case. The stabilization is not yet automated, and is
controlled by parameters:

"ODE fixed-point stabilize"
"ODE fixed-point stabilization m"
"ODE fixed-point stabilization l"
"ODE fixed-point stabilization ramp"

Need to adaptively/automatically compute these.

PyDOLFIN:

Testing stabilization in the elasticity-updated/direct demo. Looks
promising, a factor 8 (in f() evaluations, should be the same in
execution time) improvement over the stable limit for this problem.

Limited comparison against Newton/Krylov also wins with a factor 4-8
for this problem.
