More code cleanup and refactoring (#245)

* Added missing Javadocs. Adjusted many existing Javadocs to provide more details.
* Refactored data type and atomic item implementations to move casting operations to the atomic item implementations. This creates a cleaner isolation between the type adapters and Metapath items.
* Refactored names of temporal implementation classes.
* Removed some unused constants.
* Improved date and dateTime adapter unit testing to check for ambiguity and resulting time value.
* Reformatted some code.
* Performed some light refactoring to remove unused code and to improve overall code readability to make maintenance easier.
* Added asserts to ensure HTML to Mardown conversion is tested more completely.
* Significantly improved data and date/time parsing test vectors.
* Replaced Paths.get() with Paths.get(System.getProperty(user.dir)) to be more explict. Improved value creation methods in date and date/time item classes. Added many Javadocs.
* Refactored the result type used in MetapathExpression to avoid the need for a case statement. This should result in cleaner code and better performance overall.
* Removed commented out code.
* Updated some inconsistent log4j configurations to be consistent with other configurations.
* Updated dependencies through parent POM.
