Program: MKPLATECAREE

  mkplotecaree.......plate caree projection
 
  call: [x,y]=mkplatecaree(lon,lat,mapopt,direction);
 
        lon: arbitrary matrix of longitude values [deg]
        lat: arbitrary matrix of latitude values [deg]
        mapopt: map options structure as returned by MKMAPOPT
        direction: projection direction:
                   'forward': transform lon/lat to x/y
                   'inverse': transform x/y to lon/lat
 
  result: x: matrix x coordinates
          y matrix of y coordinates
 
          X and Y have same size and shape as LON and LAT (values with equal index correspond)
          but are projected and scaled according to the settings in MAPOPT
 
  The Plate Caree Projection is the most simple map projection:
  numerical values of longitude and latitude are interpreted as
  x and y coordinates without further computation.
 
  This projection conserves the lengths of the equator and of the meridians.
  Angles and areas are not conserved.
 
  Scaling is done by evaluation of arc length.
