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

-``float``
-=========
-
-Single-precision floating point number. Occupies 4 bytes. On Maple,
-the ``float`` type has a range of approximately -3.40282×10^38 to
-3.40282×10^38; the ``float`` type is subject to the same
-:ref:`overflow issues <lang-variables-rollover>` as any numeric data
-type.
-
-``float``\ s have only 6-7 decimal digits of precision. That means the
-total number of digits, not the number to the right of the decimal
-point.  You can get more precision by using a :ref:`double
-<lang-double>` (which has a precision of about 16 decimal digits).
-
-The following example declares a ``float`` value named ``myfloat``::
-
-        float myfloat;
-
-This example declares a ``float`` value named ``sensorCalibrate``,
-with value 1.117::
-
-        float sensorCalibrate = 1.117;
-
-The general syntax for declaring a float named ``var`` with value
-``val`` is::
-
-        float var = val;
-
-Here is a more extended example involving a :ref:`float cast
-<lang-floatcast>`::
-
-       int x;
-       int y;
-       float z;
-
-       x = 1;
-       y = x / 2;          // y now contains 0, ints can't hold fractions
-       z = float(x) / 2; // z now contains .5
