matlab2tikz: linux: add directory for package installation; os x and windows add dynare/contrib/matlab2tikz if it exists; (only on os x) if it doesn't add package installation dir
reporting: fix typo
Under Debian/Octave, matlab2tikz.m is already in the path, so don't add it twice
Fixed bug.
Added overloaded disp and display methods for dynSeries objects.
Check the name of the data file in @dynSeries/save method (do not erase the original data file).
Fixed bug.
