<div><h1>GradedModule -- the class of all graded modules</h1>
<div class="single"><h2>Description</h2>
<div>A new graded module can be made with 'M = new GradedModule'.  The i-th module can be installed with a statement like <tt>M#i=N</tt>, and can be retrieved with an expression like <tt>M_i</tt>.  The ground ring should be installed with a statement like <tt>M.ring = R</tt>.</div>
