Displays distributions of vector fields.

histvec_disp(V) displays the distributions of the components of the 
vector field(s) V. 
histvec_disp(V,SMOOTH) computes the velocity distributions averaged 
over SMOOTH consecutive fields. Use SMOOTH=1 for no smoothing, or 
SMOOTH=0 to smooth over all the fields (by default). If SMOOTH>1, 
press a key between each figure. 
histvec_disp(V,SMOOTH,BIN) computes the histograms among the bins 
specified by the vector BIN. If this argument is not present, the 
appropriate range of bins is estimated from the rms of the first 
histvec_disp(...,OPT), where OPT is a string that may contain one or 
more of the following letters (all by default): 
     'n': normalize the histogram (pdf) 
     'g': also displays a gaussian fit 
     'l': log-coordinate for the y axis 
   v = loadvec('*.vc7');
