[boost] GSOC 2010 - BGL Graph Connectives.

Hi, I am Tri Nguyen from South Plains College. I am interested in Graph Connectives Project of BGL. In this writing, I would like to ask two questions, and then propose my idea of doing four Connectives: union, join, intersection, and difference. My first question is: How big is the graph? Or students will try to do as big as possible. My second question is: What type of data-structures (matrix or list) will be used? I attached my ideas in the PDF file below. Please have a look. I appreciate all responses, Thank you, Tri Nguyen.
