final modification for right spacing with eclipse tool.
Merge branch 'master' into skyler

Conflicts:
	Driver.java
	SpamChecker.java
Fixed merge issues
Added output of result.txt

Doesn’t fully work, I’m getting infinities all over the place.
Something is wrong but I don’t have time to mess with it now.
Fixed results.txt generation

- changed location of test documents and results.txt : now in
(Project).test.documents
- was using new SpamChecker when should of been using original :
original used
- was only classifying documents in ham folder : changed names of files
and mixed into one folder
- was calling SpamChecker.classify(String) using file name instead of
the absolute path : used File.getAbsolutePath() instead
- in the SpamChecker constructor, SpamProbability and HamProbability
were not properly being computed because of integer division : cast to
double was added
- was missing spacing between computed document probabilities : added
- was not adding new line character after each line : added
- was not flushing buffer after each line (not necessary, but prefered)
: added
