This version throws "defined but unused" warnings which could probably
be squashed with #pragma

that there's no LOW option.

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

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

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.

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.

Perry, you might want to look this over... I only include the contents
of wirish_math.h when cpp? It's what arduino does and it works, so...

wirish init
this involved some some changes to copy-to-ide, WProgram.h, and the makefile. Separated the reset.py from the wait.py so that the program closes the serial port correctly.

perry forgot to add/edit these...

out of main to cxxabi-compat.cpp.

-Read DR after each master send, return the response.
-Added a send function to allow you to pass buffers to the SPI peripheral instead of goin a byte at a time.

The 'core' directory has now been renamed to 'wirish.' Wirish is our
version of the Arduino Wiring language.
