/**
*
* An implementation of {@link org.quartz.SchedulerFactory} that
* does all of it's work of creating a QuartzScheduler instance
* based on the contenents of a Properties file.
*
*
*
* By default a properties file named "quartz.properties" is loaded from the
* 'current working directory'. If that fails, then the "quartz.properties"
* file located (as a resource) in the org/quartz package is loaded. If you
* wish to use a file other than these defaults, you must define the system
* property 'org.quartz.properties' to* point to the file you want.
*
*
*
* See the sample properties files that are distributed with Quartz for
* information about the various settings available within the file.
*
*
*
* Alternativly, you can explicitly initialize the factory by calling one of
* the initialize(xx) methods before calling getScheduler().
*
*
*
* Instances of the specified {@link org.quartz.spi.JobStore},
* {@link org.quartz.spi.ThreadPool}, classes will be created
* by name, and then any additional properties specified for them in the config
* file will be set on the instance by calling an equivalent 'set' method. For
* example if the properties file contains the property 'org.quartz.jobStore.
* myProp = 10' then after the JobStore class has been instantiated, the method
* 'setMyProp()' will be called on it. Type conversion to primitive Java types
* (int, long, float, double, boolean, and String) are performed before calling
* the propertie's setter method.
