Detailed Description

Class COLLECTOR is an abstract class that will find and hold all the objects according to an inspection done by the Inspect() function which must be implemented by any derived class.

When Inspect() finds an object that it wants to collect, i.e. one that it "likes", then it only has to do an Append( testItem ) on it to add it to its collection, but in all cases for the scan to continue, Inspect() must return SEARCH_CONTINUE.

Later, after collection, the user can iterate through all the objects in the remembered collection using GetCount() and the [int] operator.
