.classinfo by Class name

[Justin Whear]

.classinfo is for getting information about an object at __runtime__.

For the example given here, you don't even need templates:

void mustBeFruit(Fruit fruit)
{
    writeln(fruit.classinfo.name);
}

Since Apple, Banana, and Orange inherit from Fruit, they __are__ Fruit and 
can be passed to mustBeFruit. Getting the classinfo will then allow you to 
determine, at runtime, which subclass they are.
