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

-Discussion
-----------
-
-``map()`` does not constrain values to within the range, because
-out-of-range values are sometimes intended and useful. The
-:ref:`constrain() <lang-constrain>` macro may be used either before or
-after this function, if limits to the ranges are desired.
-
-Note that the "lower bounds" of either range may be larger or smaller
-than the "upper bounds" so that ``map()`` may be used to reverse a
-range of numbers; for example::
-
-    y = map(x, 1, 50, 50, 1);
-
-The function also handles negative numbers well, so that this
-example ::
-
-    y = map(x, 1, 50, 50, -100);
-
-is also valid.
-
-The ``map()`` function uses integer math (its arguments and return
-values all have type :ref:`long <lang-long>`), so it will not generate
-fractions, when the math might indicate that it should do so.
-Fractional remainders are truncated, and are not rounded or averaged.

-Example
--------
-
-::
-
-    /* Map an ADC reading (12 bits) to 16-bit PWM (0 to 65,535) */
-
-    void setup() {
-        pinMode(0, INPUT_ANALOG);
-        pinMode(9, PWM);
-    }
-
-    void loop() {
-        int val = analogRead(0);
-        val = map(val, 0, 4095, 0, 65535);
-        analogWrite(9, val);
-    }
