Updated Makefile to read the directory where libmaple is from the
environment variable LIBMAPLE_PATH, if it exists, defaulting to the
current working directory otherwise.
Updated reset.py to look around in /dev for the Maple serial port,
prompting the user if there appear to be multiple possibilities and
complaining if there aren't any.

Fixes a bug noted by several users when using math functions like cos(),
sqrt(), etc in the Maple IDE. This bug did not seem to affect Makefile
compiles.

Fixed millis(), it was just wrong, before.
Added micros(), not extensively tested.
New implementation of delayMicroseconds(). Should be more consistent
now.
Added a handful of nvic routines to enable/disable interrupts.
Cleaned up systick

Save space on debug strings, performance. Perhaps we should consider
some form of user-facing assert.

Fixed a bug where the maximum baud rate was incorrectly set to 225000
General cleanup
Use new rcc and nvic APIs

This is just a change of macro name with zero impact on the actual
binary. Looking at page 87/1003 of the STM reference manual, bits [0:1]
are the SW register which is modifiable by software, while [2:3] are SWS
and are set only by hardware.

refactored timers and added interrupt behavior. see notes and
comments... also includes a crude vga hack that doesn't use timers.

as a temporary workaround for the fact that SerialUSB is often blocking,
this crude implementation makes the low-level C usbSendBytes function
non-blocking (with a return code of bytes sent) and implements a 2ms
timeout in the wirish write() function.
also adds begin(), end(), getDTR(), getRTS(), pending(). device is still
initialized the old fashioned way during init() so that, eg, autoreset
will work. includes a simple multi-test program.

The makefile 'install' target should upload to whatever the last build
target was, regardless of the environment's value of MAPLE_TARGET.

Commit 70a18f96b6d55d23ce58ab40ffb61f172c8f6c73 forces init() to be
called before any statically allocated object constructors for the IDE.
This adds the change to the examples for users not using the IDE.

Major build system rewrite. New and exciting:
1. Proper dependency tracking. All source files including header files
should be properly tracked and recompiled as necessary when they are
changed.
2. Build-type tracking. If the target changes from 'ram' to 'flash,'
for example, the build system will force a rebuild rather than
incorrectly link modules to a different address.
3. New targets:
The old 'ram,' 'flash,' and 'jtag' targets have been replaced with
the environment variable MAPLE_TARGET, which controls the link address.
Users can either export it to their environment, or pass MAPLE_TARGET on
the command-line. Once this is set, sketches can be compiled with 'make
sketch,' or simply 'make.'
Note: the default is MAPLE_TARGET='flash.'
The target 'install' now automagically uploads the sketch to the board
using the appropriate method.
The 'run' target has been renamed to 'debug.' It starts an openocd gdb
server.
4. Odds and ends:
-Verbose and 'quiet' modes. Set V=1 for verbose compilation, the default
is quiet.
-Object file sizes and disassembly information is generated and placed
in build/$(BOARD).sizes and build/$(BOARD).disas, respectively.
-Parallel make with -j should speed things up if you have multiple
cores.
