Views act like pointers to the actual collections, setting a view to a new
value does not alter the collection to which this view pointed previously.
<P>
The protocol used for this class mimics the way many other collection
classes are defined. For example, when used with MFC, you will see member
definitions such as <A HREF="c4_View.html" >c4_View</A>::GetSize, <A HREF="c4_View.html" >c4_View</A>::GetAt, <A HREF="c4_View.html" >c4_View</A>::InsertAt.
<P>
The elements of views can be referred to by their 0-based index, which
produces a row-reference of type <A HREF="c4_RowRef.html" >c4_RowRef</A>. These row references can
be copied, used to get or set properties, or dereferenced (in which case
an object of class <A HREF="c4_Row.html" >c4_Row</A> is returned). Taking the address of a row
reference produces a <A HREF="c4_Cursor.html" >c4_Cursor</A>, which acts very much like a pointer.
<P>
The following code creates a view with 1 row and 2 properties:
<P>
<PRE> <A HREF="c4_StringProp.html" >c4_StringProp</A> pName ("Name");
<A HREF="c4_IntProp.html" >c4_IntProp</A> pAge ("Age");</PRE>
<P>
<PRE> <A HREF="c4_Row.html" >c4_Row</A> data;
pName (data) = "John Williams";
pAge (data) = 43;</PRE>
<P>
<PRE> <A HREF="c4_View.html" >c4_View</A> myView;
myView.Add(row);
</PRE>

not actually store the result anywhere, it just looks like it.

This operation is similar to the SQL 'GROUP BY', but it takes
advantage of the fact that Metakit supports nested views. The
view returned from this member has one row per distinct group,
with an extra view property holding the remaining properties.
If there are N rows in the original view matching key X, then
the result is a row for key X, with a subview of N rows. The
properties of the subview are all the properties not in the key.

Remapping constructs a view with the rows indicated by another

Replace an entry with the contents of another row. If the

there are two cases: if this is an attached view, all the
subview rows will be copied (deep copy), whereas for an
