* Update faq.rst
* optimized file formats added to datasets/index.rst
Note: if you manage your own numerical data it is recommended to use an optimized file format such as HDF5 to reduce data load times. Various libraries such as H5Py, PyTables and pandas provides a Python interface for reading and writing data in that format.

fix bug with max_samples != int
BernoulliNB in its present form has a hard time showing the good
features, because it isn't really a linear model (XXX fix this).
A smaller test makes this easier to reproduce for users.
It is easy to overfit on the 20newsgroups dataset, by letting
classifiers learn from metadata that commonly appears in newsgroup
texts, but would be useless for identifying topics outside of this set
of newsgroups in 1993.
For example, many classifiers will tell you that three of the most
informative features are "nntp", "posting", and "host", because the
NNTP-Posting-Host header appears with different frequency in different
groups.
The fetch_20newsgroups function now allows you to ask for any of the
following kinds of text to be removed:
- Newsgroup headers (which contain lots of NNTP metadata that can
identify the group)
- Signature blocks (which often contain multiple terms that uniquely
identify the person posting, which in turn identifies the group)
- Quote blocks (which contain people's e-mail addresses and large
amounts of text from another post in the same newsgroup)
The 20newsgroups classification example takes the "--filtered" flag,
which will remove all of these. This noticeably decreases the accuracy
of all classifiers, leaving room for a better method to improve the
accuracy.
