Release Version 4.0

This release completes a long standing upgrade to the code which had left some issues, particularly

It includes the following major features:

• Air Gap Elements, AKA sliding mesh, for efficient modelling of rotating systems.
• femmcli, a command line interface for running lua scripts (thanks to @jzarl )

xfemm has two components, cfemm and mfemm. cfemm is cross-platform femm, and is the C++ code on which the toolkit is based. mfemm is a mex interface to cfemm for Matlab and Octave, and a set of functions for creating and manipulating problems.

Further instructions are provided in the individual release packages.

The linux release includes the linux binaries in the cfemm/bin directory.

The windows release includes an installer to install the binaries.
