Changing arithmetic method names for operator overloading support

[elect86]

There is a nice project here that allows to have operator overloading support.

It is basic but still a huge step for java devs.

There are some drawbacks though at the moment:

• no Netbeans 7.4+ support
• assignment operator is always a new instantiation
• fixed naming convention

    Map<String, String> binary = new HashMap<String, String>() {{
        put("+",    "add");
        put("-",    "subtract");
        put("*",    "multiply");
        put("/",    "divide");
        put("%",    "remainder");
        put("&",    "and");
        put("|",    "or");
        put("^",    "xor");
        put("<<",   "shiftLeft");
        put(">>",   "shiftRight");
        put("<",    compareTo);
        put(">",    compareTo);
        put("<=",   compareTo);
        put(">=",   compareTo);
    }};
    String revSuffix = "Rev";
    Map<String, String> unary = new java.util.HashMap<String, String>() {{
        put("-", "negate");     // jdk7
        put("---", "negate");   // jdk8
        put("~", "not");
    }};
    String   compareTo = "compareTo";
    String   indexGet = "get";
    String[] indexSet = new String[]{"set", "put"};
    String[] valueOf = new String[]{"valueOf", "of"};
