Removed all errors and inserted the Jena library to the project along
the process of removing some of the errors that was caused by not having
the Jena library installed onto the project.
Removed all errors and installed the Jena library in the process of
removing the errors. Without the Jena library, some of the files on this
project will cause errors to be thrown. This project submitted now
contains the Jena Library attached to the project. Note that three
constructors must be still be implemented. For now, they are added into
ProteinComponent.java, DanComponent.java and SequenceComponent.java to
remove the errors that the project was having.
