		Get a run-time value referencing the `Vector` class with concrete type parameters.

		Normally in Haxe, for most of the types, type parameters are eliminated at run-time,
		so there is no way to check if a value is of a type with specific type parameters.

		However, on the Flash target, the `flash.Vector<T>` values carry type parameter
		information at run-time all the type-checks (such as `Std.isOfType` and `Std.downcast`) on them
		must be done using a `Class<T>` value that also carries the type parameters. However,
		Haxe syntax does not allow creating such values and this function exists to mitigate
		this limitation.

		It should be used as such:
		```haxe
		var specificVectorType:Class<Vector<Int>> = Vector.typeReference();
		trace(Std.isOfType(vec, specificVectorType));
		```
		or using the type-check syntax:
		```haxe
		trace(Std.isOfType(vec, (Vector.typeReference() : Class<Vector<Int>>)));
		```

		It's also helpful when working with native Flash libraries, that receive Class instances:
		```haxe
		new Signal((Vector.typeReference() : Class<Vector<Int>>));
		```
