Full Discussion: Change Uppercase to Lowercase with some exceptions

1. If every character in a line is uppercase, the characters in this line need to be converted to lower case.
2. The only instance where this won't happen is if there is punctuation between characters; in this case, the uppercase letters will be changed to lower case aside from the words containing punctuation.

So, with the examples again....
(Text from file) ---> (What the text should look like)
A SUNNY DAY ---> a sunny day
A SUNNY DAy ---> A SUNNY DAy
A sunny DAY ---> A sunny DAY
A SUNNY D.AY ---> a sunny D.AY
A SUNNY DAY. ---> a sunny DAY.
a SUNNY D.AY ---> a SUNNY D.AY
