Do less check for the Yahoo! Finance auto-complete as it's output is not always the same.
Updated MEEF Historical Quote unit tests with recent changes.
Major refactoring of MEEFAPI data gathering.

Using lambdas to avoid replicating code several times and allowing
different filtering of the gathered quotes from MEEF.
Simplified the oldformat check for options.
Reworked the oldformat handling in the API.

Calculate if it's the old format directly from the GetData function
in order to avoid duplication of code. The quote handling still
needs it to determine which months to gather
(whole year, six months, each month) but doesn't use years to determine
the format.
Additional documentation.
Removed some default arguments.
Made API methods facing to integration internal and not public.
Reorganized method positions in the API.
