Create code style guide/settings

Maybe there already is, but I did not find anything in the GitHub Wiki, the Eclipse Wiki, the CONTRIBUTING.md file or the README.md file.

What are the requirements for code style when submitting changes? And were do I find those?

Maybe it would also be nice to have an Eclipse code formatter settings file, so that I can be applied automatically on each save.

According to the Eclipse Code Style as provided in Eclipse IDE, I excerpted few important factors which would be great if followed.

• Add ‘this’ qualifier to unqualified field accesses
• Add ‘this’ qualifier to unqualified method accesses
• Convert control statement bodies to block
• Convert ‘for’ loops to enhanced ‘for’ loops
• Add final modifier to private fields
• Add final modifier to method parameters
• Add final modifier to local variables
• Use lambda where possible (Not possible as of now)
• Put expressions in parentheses
• Remove unused imports
• Remove unused local variables
• Add missing ‘@Override’ annotations
• Add missing ‘@Override’ annotations to implementations of interface methods
• Add missing ‘@Deprecated’ annotations
• Remove unnecessary casts
• Remove unnecessary ‘$NON-NLS$’ tags
• Sort all members
• Remove trailing white spaces on all lines
• Correct indentation
• Remove redundant type arguments
• Add file header

I’ve proceeded to the formatting and cleanup operations. During this step I’ve had to slightly modify the formatter to increase the readability of enums. In particular, in ‘enum’ declaration -> constants, I’ve set:

• Line wrapping to all elements, every element on a new line
• Force split
• Default indentation

Due to these changes I’ve submitted the modifications as a PR #584 waiting for feedback and approval to perform the merge.
