fixed an issue causing negative accumulated rate values.
added thorough testing of the updating of rate and reaction vectors
fixed stability of test. Alot of crashes still need to be adressed.
switched off changes and reverted what had been broken. all tests pass
again. Ready to continue.
switched changed back on. Starting work on testing the shuffle
algorithm.
implemented dummy reaction class and test for the shuffeling function.
Think I have isolated the issue with old active reactions. Need a break.
