Panel fails to init

[nicolasbaum]

For actions='only' call, at certain point Panel fails to init from data stored in DFS

Note: This happens after several succesfull calls to the function exactly at the same point. I believe this has something to do with duplicated fields in the cached data

Should be fixed in v 0.0.17

Upgrade using:

$ pip install fix_yahoo_finance --upgrade --no-cache-dir

[ranaroussi]

Solved. See #17
