Couepia function

A list with 4 components: 
<code>$rect </code> is a vector of coordinates $(xmin,ymin,xmax,ymax)$ of the origin and the opposite corner of a 500 by 500 m rectangular plot. 
<code>$tri </code> is a list of vertex coordinates $(ax,ay,bx,by,cx,cy)$ of contiguous triangles covering swampy parts of the plot. 
<code>$trees </code> is a list of tree coordinates $(x,y)$. 
<code>$stage </code> is a factor with 2 levels $("mature","young")$.
