    Reads a WFDB record and Annotation file to return:

       in the current directory.

 Optional Parameters are:

 N
       A 1x1 integer specifying the sample number at which to stop reading the
       record file (default read all = N).
 N0
       A 1x1 integer specifying the sample number at which to start reading the
       annotion file (default 1 = begining of the record).
