Fixed Typo.
Changed SQLResNieveExact to SqlResNieveExact.
Created a new package for Database, org.wofecs.common.db. Created a new method in Database, connect(String schema) which creates a new JDBC connection using default settings found in the new class DatabaseSettings.  This removes some boilerplate and enables developers with different local MySQL database settings to work with identical code other than DatabaseSettings.java which can be singularly excluded from code commits. Note: I expect that there is a better solution to this simple problem. I will look into it later.
Added NONE option to PosTaggerEnum and NerTaggerEnum.
