INSTANCEMETHODS::
private::init
method::getID
Find the key for a given object. If object is not element of the dictionary, it returns nil.
EXAMPLES::
code::
a = TwoWayIdentityDictionary.new;
a.put(\test, 999);
a.put(["some", "strings"], 1200);
a.at(\test);
a.getID(999);
a.getID(1200);
a.getID(888); // nil
