ctc-striterators should build as independent top-level project (Apache2)

The ctc-striterators module has a depending on the ICloseable and ICloseableIterator interfaces in com.bigdata.striterators. Those interfaces should be moved to the ctc-striterators module and put under the Apache 2 license. The ctc-striterators module also needs some work to build independently and must bundle the necessary dependency libraries (for ant build
- since it is not using maven).
