adds test to check for null string input - fail case
test case 
	- detect empty string - test pass
test case 
	- detect found-ed string - test fail
test case 
	- not found not working due to new test case - test fail
test case - 
	- not found works - test pass
test case -
	- word found - test fail
test case - 
	- word found - test pass
word is in the list but not found - inaccurate!
word is in the list but not found
	- err spotted - word is in buffer but not pushed to storage yet thats
why didn't work!
reformating code to suite TDD, without the need to call getFileData
	- input List as one of the parameters instead of calling it internally
	- error noted as null pointer
	
Unresolved
RESOLVED 
- reformating code to suite TDD, without the need to call getFileData
	- error noted as null pointer
		- thus checked List == null first before List.isEmpty()
	
UNRESOLVED
- JUnit test case
	- test string is empty - test fail
		- wrong output due to mistype
RESOLVED
- JUnit test case
	- test string is empty - test passed
UNRESOLVED 
	- Null pointer exception @ checkCOntains due to filewriter == null
RESOLVED

JUnit Test Case 2 - pass
JUnit - 
	- uncommented 3rd test case and it works perfectly!
RESOLVED -
	- added a sortContents function
	- tried Collections.sort with test cases to ensure that  the sort works
UNRESOLVED
	- JUnit
		- test case added for sortContents for empty list 
			- test failed

	- JUnit
		- test case added for sortContents for empty list 
			- test pass
UNRESOLVED
	- JUnit
		- test case added for sortContents for non-empty list 
			- test fail
