[boost] [gsoc][graph] Hierarchical graph layout algorithms.

Hello, I'm a student interested in adding hierarchical layout algorithms as mentioned in https://svn.boost.org/trac/boost/wiki/soc2009#Hierarchicalgraphlayoutalgorit... . Is there someone available I could discuss the details for it? Are there any prospective mentors for this proposal? I'm mostly looking to discuss a proper scope for this and what Boost needs or expects from a proposal in this area. Daniel Arbelo Arrocha
