function inds = fernsInds( data, fids, thrs )
% Compute indices for each input by each fern.
%
% USAGE
%  inds = fernsInds( data, fids, thrs )
%
% INPUTS
%  data     - [NxF] N length F binary feature vectors
%  fids     - [MxS] feature ids for each fern for each depth
%  thrs     - [MxS] threshold corresponding to each fid
%
% OUTPUTS
%  inds     - [NxM] computed indices for each input by each fern
