* updated the help block for findcells(); * removed the sign variable, since that seems to be of use only when using polarity data; * flipped the relational operator of one (dbzImage,dbzThres) comparison (issue #62); * added code to deal with cells that cross the boundary between iAzim=0 and iAzim=nAzim-1 (also issue #62): such cells were incorrectly assigned different identifiers
added image to illustrate a fix for issue 62
removed all code pertaining to the sign variable from findcells() (fixes issue #51)
