function val = get(c, prop, idx)
% COMPONENTS/GET gets properties of a Components object
%
% Usage:
% val = get(c, prop [,idx])
%
% Parameters:
% c - the Components object to query
% prop - the name of the desired property
% idx - the index of the component to query (0 for the whole data)
%
% Valid properties are:
% 'stime': start time
% 'etime': end time
% 'dt': delta-t, or time increment per point
% 'npts': number of data points
% 'nc': number of components
% 'data': vector or matrix with raw data
%
% Hint: you can also access these properties like a MATLAB structure:
% nc = c.nc
% dt1 = c.dt(1)
% component2 = c.data(2);
% etc.
