The DataViewport was changing the size of Visualizers,
even when they were placed in their own DocumentWindow,
because "destroyTab" was only removing the tab from the
TabbedButtonBar, rather than the TabbedComponent.

The Visualizer class no longer inherents from OpenGLCanvas. In the future,
scrolling will be handled by a Viewport object.

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!

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

VS throws errors in several locations about ambigious type casting.
Fixed by removing the ambiguities and casting things to double.

updated the SignalGenerator to generate spikes of varying amplitudes and at a lower rate. Minor incremental changes were made to other files

changed the way that the SpikeDisplayCanvas lays out its children plots. It uses a more dynamic approach that allows plots of mixed types to be layed out in a (sort of) clean manner.

Also fixed various bugs

removed old plotting files (Tetrode, Stereotrode, Electrode) plots. They have all be replaced with SpikePlot.{h,cpp}

Signal Generator now generates fake action potentials!!! The phase dial can be used to scale up and down noise on the spikes

initial commit of SpikePlot.cpp and SpikePlot.h which define a general spike plotting object that can completely replace ElectrodePlot, TetrodePlot, StereotrodePlot. SpikePlot objects can be added to the canvas and render fine, however, eventually the Tetrode variant of the SpikePlot causes a segfault, probably due to the way that spikes are copied around in the SpikeDisplayCanvas.

began porting code from stereotrode plot to tetrode plot. It shows up in the canvas and actually shows spikes after the display is panned or zoomed at least once. Although spikes only show up in 2 of the 3 waveform axes

fixed bug in SpikeDisplaCanvas that was preventing spikes from getting rendered. The variable samplePosition was created but not initialized. I set it to 0
