% GETWINDOWOFINTERST Returns the window of interest 
%
% Usage:
%   woi = getWindowOfInterest( userdata )
% Where:
%   userdata  - see importcarto_mem
%   woi  - two-element array specifying the window of interest relative to
%          the reference annotation
%
% GETWINDOWOFINTEREST accepts the following parameter-value pairs
%   'iEgm'    {:} | integer | array
%        - The electrogram point(s) for which the window of interst is required
