% GETINDEXFORKEY returns the index of a parameter with the given key.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: GETINDEXFORKEY returns the index of a parameter with the
%              given key or -1 if the key is not found.
%
% CALL:        idx = getIndexForKey(pl, 'key')
%              idx = getIndexForKey(pl, pl)
% 
% EXAMPLES:
% 
% 1)  idx = pl.getIndexForKey('foo') % get the parameter with key 'foo'
% 2)  idx = pl.getIndexForKey(plist('key', 'WIN')) % get the parameter with key 'WIN'
