Release 0.06

This release adds the possibility of setting / getting the initial concentration of species using getValue / setValue. For this to work, you would use the syntax [ + speciesName + ]_0. So to get the initial concentration of a species A you would use getValue('[A]_0') similarly, to set the initial concentration you would use setValue('[A]_0', 10). reset() will not reset a change of the initial concentrations, but resetAll will.
