Using JAMSEL

Development Steps
1 Create an instance of CSSelector by using one of its static factory methods.
2 Get the list of identifiers encountered during the parse by calling getIdentifiers() on the CSSelector instance.
3 For each Message that you want to evaluate with the selector create a Map and populate it with the identifier names and values. Or, create an instance of ICSValueProvider .
4 Call eval() on the CSSelector instance to evaluate the selector. You can invoke either the Map or the ICSValueProvider version of the eval() method. Note, if you use the ICSValueProvider version of eval() then callbacks on the ICSValueProvider instance will be invoked to get values of identifiers during evaluation.
