/**
* A collection of wrapper classes which expose an underlying collection's
* contents as explicit types rather then just as Objects.  Essentially these
* are auto-casting collections.
*
* Each typed collection is templated based on one or more handle types
* to a const coherence::lang::Object Object. For instance:
* <tt>TypedCollection<String::View></tt> or
* <tt>TypedMap<String::View, Integer32::View></tt>
*
* Alternate handle types may also be used for added functionality,
* for example: <tt>TypedMap<String::View, BoxHandle<const Integer32> ></tt>
* produces a TypedMap which will auto-box the supplied values to Integer32,
* making statements such as <tt>hMap->put("abc", 456)</tt> possible.
*
* These typed wrappers only provide a convenience over the underlying
* collection. Thus they cannot guarantee that external usage of the
* the underlying collection will not violate the restrictions imposed by the
* wrapper. For instance Objects of a type other then those specified by
* this template may exist within the collection.  Any retrieval of those
* elements from the wrapper will result in ClassCastException.
* External usage is possible anytime the typed wrapper is passed by its
* inherited collection interface, i.e. passing a TypedMap as a plain Map.
*
* Member functions which take no input parameters cannot have their return
* type changed. Instead there will be an auxiliary function with the same name
* plus a "Typed" suffix, e.g. TypedMap::keySetTyped().
*
* Example usage:
* @code
* typedef TypedCollections::TypedMap<String::View, Integer32::Handle> StringIntMap;
* StringIntMap::Handle hMap = StringIntMap::create(HashMap::create());
*
* hMap->put("abc", Integer32::create(123));  // String's auto-boxing is utilized
* Integer32::Handle hInt = hMap->get("abc"); // no cast of return type required
* @endcode
*
