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

-Assignment Operator (``=``)
-===========================
-
-Stores the value to the right of the equal sign in the variable to
-the left of the equal sign.
-
-The single equal sign in the C++ programming language is called the
-assignment operator. It has a different meaning than in algebra
-class, where it indicated an equation or equality. The assignment
-operator tells the microcontroller to evaluate whatever value or
-expression is on the right side of the equal sign, and store it in
-the variable to the left of the equal sign [#fgross]_.
-
-Example
--------
-
-::
-
-     int sensVal;                  // declare an integer variable named sensVal
-     sensVal = analogRead(0);      // store the (digitized) input voltage at analog pin 0 in sensVal
-
-Programming Tips
-----------------
-
-The variable on the left side of the assignment operator (``=`` sign)
-needs to be able to hold the value stored in it. If it is not large
-enough to hold a value, the value stored in the variable will be
-incorrect.
-
-Don't confuse the assignment operator ``=`` (single equal sign) with
-the comparison operator ``==`` (double equal signs), which evaluates
-whether two expressions are equal.
-
-Arduino Compatibility
----------------------
-
-Assignments on the Maple are identical to those on Arduino.
