merge libmaple docs ("leaflabs-docs") into ./docs

In the past, libample documentation was forked out of this repository
because the documentation had increased in scope. For the librambutan,
and the rambutan project in general, we will try to keep documentation
closer to the source code, so the librambutan-specific documentation
should live here. Other sections of leaflabs-docs will be culled in a
following commit.

This merge attempts to maintain history by using a subtree strategy.
Followed directions at:

    http://nuclearsquid.com/writings/subtree-merging-and-you/

Full history for files should be accessible using the "--follow" flag to
git log, eg:

    git log --follow docs/source/adc.rst

It should be possible to pull patches from leaflabs-docs with:

    git pull -s subtree leaflabs-docs master

... at least until the docs in this repository diverge significantly.

+================
+ Built-in Types
+================
+
+This document serves as a reference for many of the built-in types
+which are available when programming in the IDE.  Programmers using
+the :ref:`command-line tools <unix-toolchain>` will have access to
+these types as long as they have imported `wirish.h
+<https://github.com/leaflabs/libmaple/blob/master/wirish/wirish.h>`_;
+several are defined in in `libmaple_types.h
+<https://github.com/leaflabs/libmaple/blob/master/libmaple/libmaple_types.h>`_.

+
+Integral types
+--------------
+
+.. cpp:type:: char
+
+   8-bit integer value.
+
+.. cpp:type:: short
+
+   16-bit integer value.
+
+.. cpp:type:: int
+
+   32-bit integer value.
+
+.. cpp:type:: long
+
+   32-bit integer value.
+
+.. cpp:type:: long long
+
+   64-bit integer value.
+
+.. cpp:type:: int8
+
+   8-bit integer value.  Synonym for ``signed char``.
+
+.. cpp:type:: uint8
+
+   8-bit unsigned integer value.  Synonym for ``unsigned char``.
+
+.. cpp:type:: byte
+
+   8-bit unsigned integer value.  Synonym for ``unsigned char``.
+
+.. cpp:type:: int16
+
+   16-bit integer value.  Synonym for ``short``.
+
+.. cpp:type:: uint16
+
+   16-bit unsigned integer value.  Synonym for ``unsigned short``.
+
+.. cpp:type:: int32
+
+   32-bit integer value.  Synonym for ``int``.
+
+.. cpp:type:: uint32
+
+   Unsigned 32-bit integer value.  Synonym for ``unsigned int``
+
+.. cpp:type:: int64
+
+   64-bit integer value.  Synonym for ``long long``
+
+.. cpp:type:: uint64
+
+   Unsigned 64-bit integer value.  Synonym for ``unsigned long long``.
+
+Floating-Point Types
+--------------------
+
+.. cpp:type:: float
+
+   32-bit, IEEE-754 single-precision floating-point type.
+
+.. cpp:type:: double
+
+   64-bit, IEEE-754 double-precision floating-point type.
+
+Miscellaneous Types
+-------------------
+
+.. cpp:type:: voidFuncPtr
+
+   Pointer to a function that takes no arguments and returns nothing, i.e. ::
+
+       typedef void (*voidFuncPtr)(void);
+
+.. cpp:type:: bool
+
+   Boolean type.
+
+Other
+-----
+
+.. cpp:type:: void
+
+   Not really a type. To be honest with you, this only exists here to
+   silence warnings from our documentation build system.
