[DynareDev] AIM for Dynare copyrights

Hi George,

I intend to give proper license headers to all files under the AIM/ subdirectory (since Gary has said that their are in the public domain).

By comparing to Gary's original files, I noticed that 3 files of the Dynare distribution are not in the ZIP file downloadable from the Fed's website: * SPEigQZ.m * SPQZ.m * SPSparse.m

The first two seem to be never used in the code, while the third one is simply a call to sparse() and therefore could easily be removed.

Is there any good reason to keep these files, and, if yes, who owns the copyright?

Best

Sébastien
