* int y = convert(45.0, int.class)
* String date = convert(date, String.class)

* Long date = convert(calendar, long.class); // get calendar's time into long
* Map containing ["_v": "75.0"]
* convert(map, double.class) // Converter will extract the value associated to the "_v" (or "value") key and convert it.
*
*
* @param from A value used to create the targetType, even though it may

* Please note that in addition to the 8 Java primitives, the targeted class
* can also be Date.class, String.class, BigInteger.class, BigDecimal.class, and
