+<h2>LayoutAnchors</h2>
+        A class that implements Delphi's Anchors with wxLayoutConstraints.
+<p>
+        Anchored sides maintain the distance from the edge of the
+        control to the same edge of the parent.
+        When neither side is selected, the control keeps the same
+        relative position to both sides.
+<p>
+        The current position and size of the control and it's parent
+        is used when setting up the constraints. To change the size or
+        position of an already anchored control, set the constraints to
+        None, reposition or resize and reapply the anchors.
+<p>
+        Examples:
+<p>
+        Let's anchor the right and bottom edge of a control and
+        resize it's parent.
+<p>
+<pre>
+        ctrl.SetConstraints(LayoutAnchors(ctrl, left=0, top=0, right=1, bottom=1))
+
+        +=========+         +===================+
+        | +-----+ |         |                   |
+        | |     * |   ->    |                   |
+        | +--*--+ |         |           +-----+ |
+        +---------+         |           |     * |
+                            |           +--*--+ |
+                            +-------------------+
+        * = anchored edge
+</pre>
+<p>
+        When anchored on both sides the control will stretch horizontally.
+<p>
+<pre>
+        ctrl.SetConstraints(LayoutAnchors(ctrl, 1, 0, 1, 1))
+
