Well one thing is that you don't need the type parameters on the
this function. You're basically creating a templated this inside
the templated class which is not what you want.

try this:

     class node(D, E) {
         int nid;
         D data;
         E[] in_edges; // All edges for undirected graphs go here.
         E[] out_edges; // Only used by directed graphs

         this(D data, int n) {
             this.data = data;
             nid = n;
             in_edges = new E[];
             out_edges = new E[];
         }

Another thing is that you're missing the ! to instantiate

                        v
     auto fee = new node!(string, u_edge)("Suck Moose", 1);
                        ^
