Hi guys:

I'm working on adding new test for the String class to improve the test coverage.

Rigth now, the string class has 75,42% of coverage. I found out thanks to Hapao.�

Well, these ones are methods that I don't understand.�what are they used for? how can I use them?

• correctAgainst: continuedFrom:
  
• correctAgainstDictionary: continuedFrom:
  
• lineNumberCorrespondingToIndex:
  
• correctAgainstEnumerator: continuedFrom:
  
• tabDelimitedFieldsDo:
  
• expandMacrosWithArguments:
  
• indexOfWideCharacterFrom: �to:�
  

Please, could you help me to understand them, in order to do write some test cases?
