% DESCRIPTION: Get the data property 'nsecs'.

% CALL:        val = nsecs(a1,a2,a3,...)
%              val = nsecs(as)
%              val = as.nsecs()
%
% INPUTS:      aN   - input analysis objects (tsdata or fsdata)
%              as   - input analysis objects array (tsdata or fsdata)
%
% OUTPUTS:     val  - array of with 'nsecs', one for each input
