Loads the WDFDB libarary if it has not been loaded already into the
MATLAB classpath. And optionally prints configuration environment and debug information
regarding the settings used by the classes in the JAR file.
(Optional) 1x1 integer between 0 and 5 represeting the level of debug information to output from
Java class when output configuration information. Level 0 (no debug information),
level =5 is maximum level of information output by the class (logger set to finest). Default is level 0.
(Optional) 1x1 integer representing the longest time in
milliseconds for which the JVM should wait for a data stream from
PhysioNet (default is =1000 , ie one second). If you need to change this time to a
longer value across the entire toolbox, it is better modify to default value in the source
code below and restart MATLAB.
