There isn't an easy method for erasing subgraphs. However, the subgraph
template does declare its list of children (m_children) to be public, so if
you have an iterator to the subgraph you want to delete, you can just do
sg.m_children.erase(i). Note that children_iterator isn't the same as the
iterator type of m_children. I think you can translate to it using
children_iterator::base().
