CONTAINER CLASSES

These data types can hold other objects.  They are all built up
out of more primitive Sather classes in Base.

The most important of these is ARRAY.  It extends the built-in array
providing class AREF and provides facilities for sorting, printing,
interating, and so forth.  The Sather language also allows a special
array-constructing literal syntax:
     | a, b, c |
ARRAY2 and ARRAY3 provide multiple dimensions and are built using AREF
with multiplicative indexing.

The TUP classes make it convenient to construct tuples of other types.
The TUP classes are value classes, so they are efficient; there is no
heap management involved in their implementation.  Because of Sathers
type inference, their construction can usually be acheived with:
    #(first, second)
The TUP classes "do the right thing" automatically with respect to
equality and hash values.

There are three types of container classes 
	- abstract interfaces      (such as $RO_SET{T} and $SET{T})
	- concrete implementations (such as H_SET, LH_SET and SET)
	- algorithm classes (collections of stateless algorithm functions)
