Storage TDD - SUT  Error Resolved:
	
	Resolved Error: 
		- getFileName() function not returning proper filename
		added '.ser' for the return of file name
Storage Commit - Replace all ".ser" String to Magic String:
	
	Added Magic String to StorageBase.java:
		
		- FILENAME_EXTENSION = ".ser"
		
		- The above Magic String is now protected because the child 
		classes might need them
		
		- added the use of FILENAME_EXTENSION to child classes in
		getFileName Function
