To run this in the future, install astyle (sudo apt-get install astyle),
then enter the following from the top-level project directory:

astyle --options=astyle.options --recursive "./Source/*.cpp" "./Source/*.h"

This will convert tabs to 4 spaces and ensure that brackets are on
their own lines.

For some reason, "getCustomTypefaceForFont" wasn't being called on OS X.
It probably has something to do with platform-specific code for loading
fonts. Now, in cases where custom fonts are needed, loading requires
4 lines instead of 1. Kind of a pain, so hopefully this is a temporary
solution until we can figure out what's different about Macs.

Use the following command to update the copyright year in all files,
starting in the Source/ directory:

find . -type f -print0 | xargs -0
   sed -i 's/Copyright (C) 2012/Copyright (C) 2013/g'

Works like a charm!

The main UI components now use ScopedPointers for their children,
alleviating the need to call "deleteAllChildren" or "deleteAndZero"
in the destructor.

Generic changes:

- Genuinely unused variables (-Wunused-variable): delete
  them. Sometimes add a comment if the variable is for an extension of
  the code that isn't done yet.

- Variables that became unused due to commented-out
  code (-Wunused-variable): comment out their definitions. Dirty, but
  that's because commenting out code instead of deleting it is
  dirty.

  Many of these are due to commented-out printlines that should have
  been log messages that only get emitted at high verbosity level.

Specific changes:

- SpikeObject.cpp (-Wunused-value): move initialization of loop
  variable into first for loop clause to silence the warning.

Rearrange member initialization in constructors to silence GCC
-Wreorder warnings (-Wreorder is enabled by -Wall).

These should only be defined once. Instead of making them private to
ProcessorList, define them at global scope in ProcessorList.cpp, so
ProcessorListItem can use them too.

The IntanThread can report TTL events on its 6 input channels. This was tested
with an Arduino; input detection is fast and reliable.

The IntanThread also generates its own timestamps, allowing the software to move
toward a framework in which timestamps come from input sources, rather than
from the RecordNode.

Finally, an ArduinoOutput module was added, which allows the software to
communicate with an Arduino via serial output.
