Merge pull request #80 from kpartlow/master

caching test extras
- no caching for transactional cubes (cubes with names that start with 'tx.')
- updated readme
[maven-release-plugin] prepare release 3.0.0.201411162345
[maven-release-plugin] prepare for next development iteration
- updated readme
- added in 'tx.' check for addCube
- Reduced allowed characters for n-cube name (working toward equivalency of Java variable names).
fixed typo in readme
merged
- Removed the need for the .init() method on NCubeGroovyExpression cells and instead set the input, output, and ncube references directly on the member variables (they are now public).  This eliminates another method cache and speeds up cell execution.
- Cleaned up CdnDefaultHandler code while studying it.  More can be done here if the path name can be expected to match the extension.
updated cube now keeps the cube data.
