Delete unnecessary generality in loadFile.

Browse Source 
loadFile could load mulitple files just because yaml has a feature for
putting multiple documents in one file.

Designing a linker around what yaml can do seems like a bad idea to
me. This patch changes it to read a single file.

There are further improvements to be done to the api and they
will follow shortly.
