My intention was to provide a very high level entry point to the API through the module methods so all functionality can be seen and accessed there (i.e. without knowledge of `DotMailer::Contact` or `DotMailer::DataField` etc.).

If this seems more effort than it is worth I can drop them (I have now moved them into `DotMailer::Account`, see [here](https://github.com/econsultancy/dotmailer/pull/3)).

WDYT?
