When using FASTMATH in combination with the StabilityChecker it will not work due to
https://stackoverflow.com/questions/22931147/stdisinf-does-not-work-with-ffast-math-how-to-check-for-infinity and https://community.intel.com/t5/Intel-C-Compiler/icx-2021-3-0-bug-isinf-wrong-result/m-p/1316407#M39279
This MR adds more documentation to make people aware of the situation and extends the StabiltyChecker by providing a limiterValue which could be used for checking as an alternative to checking for non-finite values.
Fixes #184 (closed)
