Weird behavior was observed during fwrite when files were only opened
with "a". fwrite did not write the expected number of bytes (probably
augumented things with a \n or \r). This caused serious problems parsing
the dumped files in matlab. Forcing a binary fopen option fixed things.

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

This fixes a segfault that happened when no electrode was selected on a spike detector (e.g., with no electrodes added); getSelectedItemIndex returns -1 in this case, which was causing an array bounds segfault in drawElectrodeButtons.

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.

Altered the default settings of SignalGeneratorEditor and SpikeDetectorEditor to reflect the desired values for debugging the spike viewers

fixed bug where the max size of a spikebuffer was 256 bytes, this is too small for tetrode spike, this value is not determined by a constant defined in SpikeObject.h
