This PR integrates the last version of the PaRSEC DTD systems as a possible runtime system for the Chameleon algorithms, and is provided by @reazulhoque
(Fix partially issue #4)
For now almost everything is working in shared memory with current version of PaRSEC master (more precisely with mymaster from my fork, but it should not change anything). The only issue before merging this pull request is the bug related to any hierarchical tree in QR/LQ factorization.
