% CONVERT perform various conversions on the ao.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: CONVERT perform various conversions on the ao.
%
% CALL:        ao = convert(ao, pl)
%
% PARAMETERS:
% 
%              'action' - choose a conversion to make [default: none]
% 
% Possible actions:
% 
%    Unit conversions:
%         's to Hz'   - convert seconds to Hz in the yunits of this AO.
%         'Hz to s'   - convert Hz to seconds in the yunits of this AO.
% 
%    Data conversions:
%         'to cdata'  - convert the data in the AO to a cdata type.
%         'to tsdata' - convert the data in the AO to a tsdata type.
%         'to fsdata' - convert the data in the AO to a fsdata type.
%         'to xydata' - convert the data in the AO to a xydata type.
