Changes in FileHandler
The main issue resolved is that FileHandler now returns a Command which the user tells to execute, rather than the execution being performed in the constructor of a CopyFile or MoveFile Command.
FileHandlerTest also now creates and destroys temporary test files.
A logger was also added to replace the System.out print statements. The logger prints to the console as defined by a very basic default log4j.properties file that was added to the resources directory. This directory is by default included in the classpath so the maven project picks it up and applies it at run time (e.g. in CommandFactoryTest).
