%program calls function gbplot to plot greene bomber acoustics data
% emat = file name in matlab workspace that has data to be plotted
%	 program assumes data file has seven parameter columns and n data columns as:
%		col 1:   Yearday.time
%		col 2:   latitude (degrees and fractions of degrees)
%		col 3:   longitude (- for Northern Hemisphere and West)
%		col 4:   Transducer frequency
%		col 5:   Minimum depth of acoustic bins (meters)
%  col 6:   Maximum depth of acoustic bins (meters)
%  col 7:   Depth interval of acoustic bins (meters)
%  col 8-n: Volume backscattering data (sv, not logged)
% Thus each row has a single time interval of acoustic data
% yint = equals the number of depth bins in data file and is deteremined
%        by maxdepth/depthint after mindepth set to 1 meter and maxdepth adjusted appropriately. 
% xint = equals the number of horizontal bins and is determined in the
%        the function
% figtitle = title to go on plot
%
% nplot = number of plots - max of four
