 DRAWVEC draw arrows for vectors

 DRAWVEC drawvec(xo,yo,um,vm,atheta,lcolor) is a routine to 
         draw vectors. This is a fairly low-level routine
         in that in does no scaling to the vectors.  This function
         is called primarily by VECPLOT and returns the handle
         of the vector object drawn.

 Inputs: xo,yo  - vector origins; arrow eminates from this point
         um,vm  - vector magnitudes
         atheta - arrow-head angle, in degrees
         lcolor - linecolor , 'r' = red, etc.

 Outputs: hp    - the handle to the vector object drawn

 Call as:  hp=drawvec(xo,yo,um,vm,atheta,lcolor)
