Improve colormap in check_audapterLPC

[cwnaber]

According to Carrie, the colormap for the spectrograms in check_audapterLPC is ok, but the dynamic range is too low. And at some point, Ben got a rainbow colormap.

The colormap is controlled by varycolor on line 293, which we got from the file exchange and is actually in the current-studies repo. So that's not great either, that this free-speech function has a current-studies function as a dependency.

%Set up colors. Using varycolor allows for any number of vowels
plotColors = varycolor(UserData.nVowels);

@cwnaber : Good catch on the varycolor dependency; agree that this should be changed to not rely on current-studies. This is unrelated to the spectrogram colormap, though -- it just affects what line/marker colors are used to plot on top of the spectrograms and in the 2D vowel space plot. The colormap is set when the spectrogram is plotted (in this case, by show_spectrogram).

In that case, @parrell probably needs to move the "commonmcode" folder to the bottom of his matlab path. There are probably conflicting show_spectrogram functions, since we have our own in free-speech\experiment_helpers\show_spectrogram.m. This is something I do in step number 7 of this KB doc when setting up new computers.
