Hello! My name is Youup Kim. My colleague Youstina Attia (@youstina-attia) and I created this PR for an undergraduate Software Architecture course at the University of Calgary.

Our assignment requirements were to perform refactoring and introduce a software pattern into a pre-existing repository. Yours (Norconex Importer) was one of the repositories we selected.

This PR was not tested!!! We don't want to break your project, but we also most likely don't have the time commitment to test our changes.

We opened this PR so that if any current or future maintainer is interested, they can give it a look and decide if something like this is desirable for the repo.

• They could outright reject this PR, and ignore it entirely. (Or give us feedback that we'll learn from going forward)
• Reject the PR but implement the ideas themselves in their own way.
• Edit and/or test this PR themselves with (hopefully) some of the work already done.
• Merge it anyways if they are a dangerous daredevil that decides the changes are sufficiently safe.

This PR introduces a Singleton Pattern for all of the util classes. This would allow the class to be tested and extended for future maintainability and extensibility.

We also wanted to note that the BufferUtil.java file could be removed as it is never referenced in any part of the project.

Thank you for your interest in this project. There is no need for this project to keep singleton instances around for utility classes. Nothing prevents adding unit tests to static methods. You are welcomed to add more Junit test coverage where you feel more are needed.
