* remove unneeded "this."
* shorten code

* use (Key|Window)Adapter instead of Key(Key|Window)Listener when only
  implementing one method
* fix comments

The 3D canvas was not added to the JFrame.

* use tabs instead of spaces for indentation
* remove trailing spaces

Updated .gitattributes and .gitignore to provide better support for enforcing LF eol and preventing binaries from entering the repository

* com.syncleus.test.dann -> com.syncleus.dann
* remove no longer required includes

* sources and resources were only moved, not changed
* moved test sources into separate dir
* adjusted ant build script (targets tested)
* added Maven project file (projects/java_dann_examples/pom.xml)
* added Maven parent project file (projects/dann/pom.xml)
* moved some stuff into parent project, to reduce duplication
* added all-projects maven file for convenience (projects/pom.xml)
* added maven build dirs to gitignore
* renamed dann to dann-core (maven artifactId)

To build all of dann (core + examples), use either of:
* projects/dann/pom.xml
* projects/pom.xml

To build only core, use:
* projects/java_dann/pom.xml

It is NOT possible to build the examples directly with:
* projects/java_dann_examples/pom.xml
Except you have the required version of dann-core deployed
into your (local) maven repo with:

	cd projects/java_dann/
	mvn install

fixes ticket:141 more thoroughly by throwing a ComponentUnavailableException which is included in this commit.  ComponentUnavailableException is intended to be a start towards a self-configuring, self-repairing framework that is aware of missing components or configuration - OR at the very least, can inform the human operator how to fix the situation.  it might also be called FeatureUnavailableComponent ... worth considering.

Fixed issue from earlier commit where lib/build directories didnt get commited. Added clear() to mutable graphs and MutableGraph interface.
