issue 22+37, pretty stable, compiles on my machine

will do: move power on delay, let no cycles be wasted. make leds.py nicer. add another way to save power, hierarchy must only be active during data transmittion, after that even led 14 can be switched off when the top leds are still active i think. will adjust initial rgb channel gammas as soon as i get my hands on final hardware

enjoy =D

 ``leds`` - LEDs
 ===============
+The ``leds`` module provides functions to interact with card10's RGB LEDs.
+This is the 11 LEDs above the display and 4 LEDs on the underside of the
+top-board, in the four corners.
 
-.. py:function:: leds.set(led, color)
-
-   Set one of the card10's RGB LEDs to a certain color.
-
-   **Example**:
-
-   .. code-block:: python
-
-      import leds, color
-
-      # Set all of the top LEDs to red
-      for i in range(11):
-         leds.set(i, color.RED)
-
-   :param led:  Which led to set.  0-10 are the leds on the top
-      and 11-14 are the 4 "ambient" leds.
-   :param color:  What color to set the led to.  Should be a
-      :py:class:`color.Color` but any list/tuple with 3 elements
-      will work just as well.
-
-.. py:data:: leds.BOTTOM_RIGHT
-
-   Index of the LED in the bottom right of card10.
-
-.. py:data:: leds.BOTTOM_LEFT
-
-   Index of the LED in the bottom left of card10.
-
-.. py:data:: leds.TOP_RIGHT
-
-   Index of the LED in the top right of card10.
-
-.. py:data:: leds.TOP_LEFT
-
-   Index of the LED in the top left of card10.
