public static function areEqual(o1:*, o2:*):Boolean
Checks if objects are equal.
First thi method compare objects using o1 == o2
.
If it returns true then the method returns true.
Otherwise it will be checked if both objects implement org.as3coreaddendum.system.IEquatable
interface and then use o1.equals(o2)
.
Parameters
o1:* — a Number object to evaluate.

o2:* |
Boolean — true if the value is NaN (not a number) and false otherwise.
