function filtered_data = fcsselect(data, idx)
%FCSSELECT selects events in DATA corresponding to indexes IDX. As with
%normal matrix indexing, IDX can be a list of indexes or a logical array
%containing 1's for desired elements and 0 for unwanted elements.
%
%   Updated 20120816 JW: Now can take a list of lists of indexes and
%   returns a struct array of data.
