LCONTOUR4 contour a scalar field on a FEM grid.
   LCONTOUR4 contour a vector of scalar values across a FEM grid.
   LCONTOUR4 accepts a vector of values to be contoured 
   over the provided mesh.  LCONTOUR4 expects the element 
   file to be either 3 or  4 columns wide.  If elems is 4 columns 
   wide, LCONTOUR4 assumes the first column is the element number 
   and strips it away.

 Input:    elems - list of nodes per element
           x,y - xy locations of nodes; each must be 1-D
           Q - scalar to be contoured upon; must be 1-D
           cval - vector of values to contour

           The parameter/value pairs currently allowed in the lcontour4  
           function are as follows ( default values appear in {} ) :

                Color       {'r' = red}
                LineStyle   {'-' = solid}
                LineWidth   {0.5 points; 1 point = 1/72 inches}
                MarkerSize  {6 points}

           See the Matlab Reference Guide entry on the LINE command for
           a complete description of parameter/value pair specification.

           The idea and some of the constructs used in pv decoding
           in this routine come from an unreleased MathWorks function 
           called polar2.m written by John L. Galenski III  
           and provided by Jeff Faneuff.

 Output:  lcontour4 returns the handle to the contour line drawn

 Call as: h=lcontour4(e,x,y,Q,cval,p1,v1,p2,v2,...)
