Corrfitter

=======================
corrfitter updated for version 10.0 of lsqfit. The most important
new feature is the ability to change fitter keyword values in the middle
of fit chain, by including a dictionary with the new values as
an entry in the models list. This allows far more control over the
individual fits in chain of fits.

There are minor incompatibilities that mostly affect chained fits and are
mostly internal. The list of chained fits (fit.chained_fit) now contains all
fits, including the wavg fits done after a parallel fit. The output from
fit.formatall() differs accordingly. Another change for all fits: bootstraps
are initiated using the fit (not the fitter, as before) -- eg,
fit.bootstrapped_fit_iter(10).

========================
- Small bug fixes for edge cases.

- Documentation improved.

=========================
- Fixes CorrFitter.bootstrapped_fit_iter which was broken in the move
to v6.0. Thanks to Enrico Rinaldi for pointing this out.

- Adds a bootstrap analysis to the etas.py example.

==========================
Minor update.

- Modified tests to account for change in numpy.

- Cleaned up some obsolete tests.

- Reorganized documentation.

- Added warnings if Corr3 attempts to use tpa, tpb, or transpose_V,
all of which are deprecated.

========================
Even more minor update than the last. This has tiny improvements to the
installation script (setup.py) and distribution file layout to make
installation more robust, with less opportunity for confusion on the
part of the user.

========================
Very minor update.

- Improved installation script.

- Documentation fix.
