[feature] preprocessors about jcodemodel HOT 2 OPEN

Q : Why not do a list of script with parameters , eg new BeanScript().withClass(myJCMClass).apply(jcm) ?
A : first, for the reason of ordering : the order in which those scripts would be applied would impact the result. Secondly, because calling the script again in another par of the code could lead to issues, therefore the JCM must be used to ensure there is only one instance of each available.

Another use case : the generation of a cached value from a generator method.

typically, either the method takes no argument, therefore one item is cached. Or the method takes an argument, and a map stores the cached generated items .

By applying the processor on those two methods :

    private int makeNext(int value) {
        return (value + 1);
    }

    private int make100() {
        return  100;
    }

It results in the following code being added :

    private HashMap<Integer, Integer> next = new HashMap<Integer, Integer>();
    private int hundred = null;


    public int getNext(int value) {
        int ret = next.get(value);
        if (ret == null) {
            ret = makeNext(value);
            next.put(value, ret);
        }
        return ret;
    }

    public int getHundred() {
        if (hundred == null) {
            hundred = make100();
        }
        return hundred;
    }

Still needs to be synchronized if required, to add comments, and to clean the code.
