- Closed all Scanner and Buffered Readers

- Added Some Java Doc

- ReverseString - took space out of between each letter so "Zachary" to
"yrahcaZ" instead of "y r a h c aZ"

- bfs - Trying to repair this class but need to research bfs more

- dfs - Trying to repair this class but need to research dfs more

- Added new Classes
1) OctalToBinary - Not done
2) BinaryToOctal - Not done
3) OctalToDecimal - Not done
4) Graphs

-Added the dataStructure Graphs (Unfinished)
