+{-| Floating Action Button. From the
+[Material Design Specification](https://www.google.com/design/spec/components/buttons-floating-action-button.html):
+
+> Floating action buttons are used for a promoted action. They are distinguished
+> by a circled icon floating above the UI and have motion behaviors that include
+> morphing, launching, and a transferring anchor point.
+>
+> Floating action buttons come in two sizes:
+>
+>  - Default size: For most use cases
+>  - Mini size: Only used to create visual continuity with other screen elements
+
+This constructor produces the default size, use `minifab` to get the mini-size.
+
+Example use (colored with a '+' icon):
+
+    import Material.Button as Button
+    import Material.Icon as Icon
+
+    fabButton : Html
+    fabButton = fab addr model Colored [Icon.i "add"]
