irc2 post merging using position and amplitude of clusters

use gaussian kernel smoothing (make sure i get half a fall off at half the mindist). normalize by projecting a uniform field and ensure uniform field back.

advantage of this approach is robustness to where the peak site is located in determining the peak location.

gaussian kernel convolved, maximum slope at the minimum separation distance (sigma=d_min)
inferring spike position using PC1 is more precise than using other components
Great study music helping me to focus
