UML Modeler Code

- minor changes to detectAttribute
- integrating with detectClass
- adding testing main()

I added the detectClass method in the modelGenerator class with some other methods needed
I added an enum 'declarationKeyWords' in the controller package

I made minor adjustments to the OOClass and OOObject classes (I just gave the boolean instance variables a default initialization value of false and gave initialized the reference types with null)

Detect Attribute implemented

- fixing bug: clearing allowed tokens array before begining the loop iteration ... makes the detection fails always!

- checking the currentToken if it belongs to the list if allowed tokens or not

- Adding detectMethod to Modelgenerator
- Adding getters/setters to OOMethod
