Change '\n' to endl in test programs.

Test:
	FDSet
	SeqCltn:: hash(), isEqual(), occurrencesOf()
	Arraychar::compare()
	removeAll()
	Heap::removeId(), LinkedList::removeId()
	Iterator(Heap) object I/O

Per class implementaton of deepCopy() ?:
	classname* classname::deepCopy() { return classname::castdown(Object::deepCopy()); }

RevIterator (wouldn't have to implement for unsequenced collections).

AVLTree and SplayTree

Add support for microseconds to class Time.

LinkedList::remove(const Object&) -- Object's Link is modified.

Add Process:wait on multiple Semaphores?

When exceptions are implemented:

	-  Check for memory allocation failure in new, malloc, and realloc.

	- Fix readFrom to delete readFromTbl in case exception is raised.

	- Fix storeOn to delete storeOnTbl in case exception is raised.
