pslice2

 PSLICE2  Just like pslice, but no color legend bar is drawn
  USAGE: pslice2(x,y,u,cax)
 x is array of x points
 y is array of y points 
 u is array of data
 cax is range of data to map  (autoscales if not supplied)

 EXAMPLE:  pslice(x,y,temp,[10 22],'Temperature')  
                Plots the variable temp from 10 to 22 deg, and labels the
                colorbar legend as "Temperature (C)"
