averageSentenceLength.java

/* 
Notes: 

Possible Questions:
1) Is there default behavior needed
2) Persistant data a required feature...IE retain past scans for comparison
3) Identify any of the largest sentances or just show length?

Testing/Erros to be handled
-input files doesnt not exist
-command line argument checking 
-empty input file
-paragraph indentation strangeness
-quotation marks
-no delimteres default behavior ? returns or paragraphs
-non text file? 
-public interface?
-performance metrics?
-Do zero char sentances count !!
-elipses?
-should we strip leading whitespace
-command line issues

Should each role be responsible for their own documents: 
1. Project Management -> Agendas, notes, task assignments, and ProjectPlanTemplate.md.
2. Documentation lead -> Design Documents (RequirementsDocumentTemplate.md), and help documents.
3. Developement Lead -> Code
4. QA Lead -> Tests.
This roughly means that 1 and 2 will be adding changes for stage 1, and 3 and 4 will be adding changes for stage 2. This does seem to follow the waterfall method. 
Or should each team member be committing is each document and therefore at each stage? I have a hard time dividing up each document and probably <300 lines of code four times. Ie:
All four people commit to -> ProjectPlanTemplate.md
All four people commit to -> RequirementsDocumentTemplate.md
All four people commit to -> Code
All four people commit to -> Tests
So which way is required or can we do it either way?
