FIX: make FastICANode test more robust
FIX: make test_SFA2Node even more robust
FIX: updated copyright date
FIX: Fix wrapping of sklearn 0.11 classifiers
FIX: disable pp support if server can not start

Being able to import pp is not enough to be sure that
pp works. For example in a low memory situation, the following
can happen:

>>> import pp
>>> server = pp.Server()
[...]
OSError: [Errno 12] Cannot allocate memory

This fix just disables pp support if the server can not be started.
ERF: make sklearn nodes automatic testing more robust

The previous solution was actually ignoring the special definitions
in NODES.
FIX: fix error in automatic testing for MultinomialNB.
NEW: add support for newest sklearn algorithms
OTH: updated CHANGES and COPYRIGHT
DOC: bumped version number after release ;)
ENH: 2 stage optimization for FastICA found in current AFNI
ENH: FastICA -- primary_limit -> coarse_limit + default to None

Introduced to make things a bit clearer since there is already "fine tuning"
stage where optimization switches to used_g upon reaching the limit.
Calling the limit "coarse" instead of "primary/secondary" would help to preserve
original messages/logic thus not confusing existing users, while still allowing
to kick in gFine before reaching the limit
ENH: FastICA - test having some coarse_limit
DOC: moved coarse_limit description under FastICA and removed signature (present elsewhere)
Merge pull request #4 from yarikoptic/master

FastICA -- introduce coarse_limit to trigger switching to fine_g before reaching target limit. 

Thanks to Prantik Kundu and Yaroslav Halchenko for the patch!
FIX: make pip work without explicit URL.

now we point directly to the tar archive in the
download_url field of the setup.py file.
DOC: added an example to GeneralExpansionNode and made the documentation more explicit
DOC: indicated what expansion failed in the tests of GeneralExpansionNode
FIX: made code and documentation consistent regarding the parameter k in invert_exp_funcs2
Merge pull request #6 from AlbertoEsc/documentation-general-expansion-node

Documentation general expansion node.

Thanks to Alberto Escalante!
