Maple v3.0.0 Alpha

This update adds most of the functionality I wanted to be in Maple.
The code was cleaned up and the javadocs were made more consistent and descriptive.

Changes:

• Merged and improved classes from MapleTree into Maple
• General improvements
  • Removed redundant mutexes
  • Simplified connecting elements
• Remove creation methods (use normal constructor instead)
• Make DataValue abstract, implemented by Dynamic and Static
• Improve toString output
• Add more utility methods (see the readme)
