------------------------
my_stepCSD.m: Gaussian smoothing function of the step iCSD method was changed. The old one was based on 
expanding the N electrode position data-points to a fixed resolution of 200 points. This might lead to 
round-off errors.

To do:
----------
1) Possibility to store CSD matrix or export it to workspace
2) Number showing up when mouse is pointing at a pixel in the plot
dcm_obj = datacursormode(fig);
set(dcm_obj,'DisplayStyle','datatip','SnapToDataVertex','off')
(this can be done in the figure mode)
3) Line plots of individual CSD traces
