clSPARSE v0.6.0.0 open source beta release

This is the open-sourcing of the ACL clSPARSE project, tagged as v0.6.0.0 as part of ACL 1.0 beta 1. The functionality provided in the release is detailed on the projects main README file. Project build instructions and a few performance graphs are provided on the project wiki.

We release clSPARSE as beta software (0.y.z.w) early to the community to elicit feedback and comment. Please leave bug reports and feedback on the github repo's issues tracker. This comes with the expectation that we may incorporate breaking changes to the API that might require early users to recompile, or rewrite portions of their code as we iterate on the design.
