[FieldTrip] [ANN] OpenMEEG 2.4 release

[Alexandre Gramfort]

Dear community,

We are pleased to announce the new 2.4 release of OpenMEEG.

Last release from OpenMEEG was a while ago but a number of
developments and bug fixes have been done since then and just needed
to be released.

A few highlights
============

    - Support for non-nested geometries (e.g. hole in skull)

    - Python bindings work now for both Python 2 and 3 in Windows,
Linux and OSX platforms.

    - Openmeeg can now be installed though conda. See installation for
details, this installs the OpenMEEG libraries, binaries and bindings.

    - Project was moved to GitHub:
https://github.com/openmeeg/openmeeg and continuous integration is now
done with Travis and Appveyor that also generate nightly builds for
all 3 platforms.

    - Improved web site at https://openmeeg.github.io/

    - New tutorial page at : https://openmeeg.github.io/tutorial.html

    - Optimized parallel computation of the D operator (should
accelerate Head matrix computation with OpenMP parallel binaries)

    - All files saved and written by OpenMEEG are now in Matlab 7.3 /
HDF5 format so can be accessed just with load and save in Matlab.

Thanks
======

Many thanks to François Tadel to help us with the Brainstorm
integration and to Sarang Dalal for revamping the Fieldtrip code to
better support this new version.

Warning
======

If you have used OpenMEEG before you will need to recompute all the
intermediate files to use them with the version 2.4
