fixes #26 made lock recovery more efficient by caching and batching
Fixes #98 - Moved API & MapReduce classes to their own module.
Organized packages in core module.  Created FluoFactory class so users
can create FluoClient or FluoAdmin from API using reflection.  Core now
generates test jar to allow other modules to use utility test classes.
Formatted Maven pom files to use two spaces.  Configuration class was
renamed to Environment.
