Heliosearch v0.04

This is Heliosearch v0.04
Heliosearch is forked from Apache Solr and includes the following additional features:

• Off-Heap Filters to reduce garbage collection pauses and overhead.

• Removed the 1024 limit on the number of clauses in a boolean query. For example: q=id:(doc1 doc2 doc3 doc4 doc5 ... doc2000) will now work correctly without throwing an exception.
• Deep Paging with cursorMark. This is not yet in a current release of Apache Solr, but should be in the future.

• nCache - the new Off-Heap FieldCache to reduce garbage collection overhead and accelerate sorting, faceting, and function queries.
