* new function SD_task_dump() for debuging display
* new function SD_daxload(char*) to load a DAX file
(see http://vtcpc.isi.edu/pegasus/index.php/WorkflowGenerator)
+ * SD_task_dependency_exists() can now cope with having one of its
+ arguments NULL. If so, it tests whether the other argument has any
+ dependency.
+ * Introduce typed tasks. Specify its kind and cost at creation.
+ At scheduling, just give where it should be placed, and the cost
+ for each involved resource is automatically computed.
+ Existing constructors so far (more to come of course):
+ - SD_task_create_comm_e2e() for end-to-end communication
+ - SD_task_create_comp_seq() for sequential computation
+ Use SD_task_schedulev() / SD_task_schedulel() to schedule them.
Bug fixes:
* GTNetS wrappers should now be usable again (and betterly tested too)
