adding the feature of adaptive time stepping scheme.
The test case is \Tests\examples\kinetic_reaction_SeqDeg\seqdeg
This test case is not correctly running yet.

We still need to get the information of Newton iterations in order to do that.
Nori will think about that.
fix a bug. zeroObject() was called in releaseObject()
fix comile errors
fix compile errors
make destructor virtual and fix compiling errors with g++
