#30 Unresolved warnings

[Ismael]

I imported the sources of release 2.4 into Eclipse and in the "Problems" view of Eclipse, there are 201 unresolved warnings. If you use Eclipse to develop MOEA, you should activate some warnings detection (Preferences -> Java -> Compiler -> Errors/Warnings) and resolve all warnings. This is a good practice.
Some warning types found include :
- Potential null pointer access: The variable may be null at this location
- Redundant superinterface Serializable
- Declared exception not actually thrown by the method
- Parameter hiding a field from enclosing class
- Raw type : references to generic type should be parameterized
Here is attached an excel file listing all the 201 warnings found by Eclipse (in "Problems" view).
