function icq4struct=icq4info(command,option)
%ICQ4INFO
%   ICQ4INFO provides information on an input fem_icq4_struct
%   or an icq4 file.  It optionally returns the icq4 data in
%   a fem_icq4_struct, and can read only the header information.
%
%   Input:  arg1  -  fem_icq4_struct or icq4 filename
%           arg2  -  If arg1 is an icq4 filename, then
%                    arg2 can be either 0 (read only
%                    file headers) or 1 (read entire file).
%                    If arg1 is a fem_icq4_struct, then
%                    arg2 is ignored.
%           arg2 can also be a [1X2] vector; the first element
%           is the "read" option above, and the second element
%           is whether or not (0|1) to post the display figure.
%           This option is ignored if arg1 is a fem_icq4_struct.
%           The default is to display the figure.
% 
%  Output:  fem_icq4_struct - If arg1 was a filename, ICQ4INFO 
%           returns the fem_icq4_struct if an output argument 
%           is provided. icq4 file information is displayed to 
%           a new figure.
%
% Call as: >> icq4info(icq4filename)
%          >> icq4=icq4info(icq4filename);
%          >> icq4=icq4info(icq4filename,0|1);
%          >> icq4=icq4info(icq4filename,[0|1 0|1]);
%          etc...
