**Usage:**`gendot(L,Filename,Type)`

Generates a dot file from a list L representing a graph. It receives the basename Filename (without extension) of the output .dot file. Each element of L is a node in the graph, represented by a tuple (Identifier, Label, Edges), where Edges is a list of the outgoing edges of the current node, and each element of Edges is either an Identifier ot a tuple (Identifier,Label). In all cases, Labels are atoms. Type indicates the type of graph. If the graph is a Tree, then final nodes are represented by boxes. In all other cases, nodes are represented by circles
