function mrgann(varargin)
%
% mrgann(recName,annName1,annName2,outAnn,verbose)
%
% Wrapper to WFDB MRGANN:
% http://www.physionet.org/physiotools/wag/mrgann-1.htm
%
%
% Reads a pair of annotation files (annName1, annName2) for the specified
% record (recName), and writes a third annotation file (specified by outAnn)
% for the same record. Typical applications of MRGANN include combining annotation
% files that apply to different signals within a multi-signal record, and replacing
% a segment of an annotation file with annotations from another file. MRGANN cannot
% concatenate annotation files from different records (e.g., segments of a multi-segment record).
%
%
%Required Parameters:
%
% recName
% String specifying the name of the record in the WFDB path or
% in the current directory.
%
% annName1
% String specifying the name of the first WFDB annotation file to be
% merged.
%
% annName2
% String specifying the name of the second WFDB annotation file to be
% merged.
%
% outAnn
% String specifying the name of the output WFDB annotation file
% containing the merged annotations.
%
%
% Optional Parameters are:
%
% verbose
% Boolean. If true warns about simultaneous annoations with matching
% chan fields (default = true).
