Kruno Tomola Fabro df0bf6fa5f Database interface refactor.
DbAccessor:
 -Guarantees that access to Vertex and Edge is possible only through
 Vertex::Accessor and Edge::Accessor.
 -Guarantees that changing Vertex and Edge is possible only using
 Vertex::Accessor returned by vertex_insert() method and
 Edge::Accessor returned by edge_insert() method.
 -Offers CRUD for Vertex and Edge except iterating over all edges.

Squashed commit messages:

First step in database accessor refactoring done.
It's compiling.
All tests with exception of integration_querys pass
