Pretty big change. Things now pass up errors that can be handled by the
caller. This brought about a lot of change. Errors attempt to be
descriptive of where they came from and notify user of the api what
potentailly caused the error. Also renamed go-halo5-api.go to a more
suitable name, http.go. This might change in the future if we implement
the http.Client interface
moved all metadata.go function calls into method calls for the Halo
struct. This will make it easier to encapsulate baseurl, apikey, blah
blah, and also makes the code a little bit more readable. Stats.go and
profile.go are to follow.
Still need to implement http.Client interface and look over the code in
go-halo5-api.go. Most likely needs to break out and be cleaned up
