Remove reST documentation, attendant updates.

The documentation covers topics not specifically relevant to libmaple,
so it doesn't make sense for it to be part of the libmaple source
distribution.

Delete the docs/ tree, and prepare libmaple for use with the new
leaflabs-docs repo, which will contain the docs from now on.

* README: update to reflect this change

* support/doxygen/Doxyfile: This is the old docs/Doxyfile

* Makefile: Add a doxygen target

* wirish/comm/HardwareSerial.h: fix reference to docs/.  The comment
  informing maintainers that the HardwareSerial interface is
  documented by hand refers to the docs/ tree, which no longer exists.
  Update it to refer to the separate leaflabs-docs repository.

* support/scripts/copy-to-ide: No longer build the documentation

-digitalRead()
-=============

-Reads the value from a specified digital pin, either :ref:`HIGH
-<lang-constants-high>` or :ref:`LOW <lang-constants-low>`.

-Discussion
-----------
-
-If the pin isn't connected to anything, ``digitalRead()`` can return
-either HIGH or LOW (and this will change in a way that seems random).
-
-Example
--------
-
-The following example turns the LED on or off when the button is pressed::
-
-    void setup() {
-      pinMode(BOARD_LED_PIN, OUTPUT);
-      pinMode(BOARD_BUTTON_PIN, INPUT);
-    }
-
-    void loop() {
-      int val = digitalRead(BOARD_BUTTON_PIN);   // reads the input pin
-      togglePin(BOARD_LED_PIN, val);
-    }
-
-Arduino Compatibility
----------------------
-
-The Maple version of ``digitalRead()`` is compatible with Arduino.
