% DESCRIPTION: FIL a wrapper for the LISO fil executable.
%
% CALL:        utils.bin.fil('foo.fil')
%              utils.bin.fil('foo.fil', 'foo2.fil', 'foo3.fil', ...)
%              utils.bin.fil('foo.fil', 'foo2.fil', 'foo3.fil', '-c', ...)
%
%              >> a = utils.bin.fil('foo.fil') % get result as AO
%              >> f = utils.bin.fil('foo_iir.fil') % get result as MIIR 
% 
%              >> utils.bin.fil % get fil help
% 
% INPUTS:
%          'filename'  - one or more .fil filenames
%          'option'    - pass options to fil
