bare gem structure as created by bundler
provide a very rough cut and basic implementation

as extracted from a throwaway scripts, slightly adapted and fixed to
work in a standalone rake file. Still needs a lot of refactoring, but
it's a start.
set requirements straight

we actually need to include eson-more explicitly since it's not part of
the eson package.
fix bulk loading of a seed file

an error was tucked away in the bulk loading of the seed data file.
introduce base path constants

so we can configure the path at the head of the script and don't need to go through the whole script when the path layout changes.
