+<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))
