Subject: Add various getters to task structure:
X-Git-Tag: SVN~987
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/012d0bddbd960e51d7ddff501523d9a994b0d8dd

Add various getters to task structure:
 * list of preceding/following tasks:
    SD_task_get_parents(task) and SD_task_get_children(task)
 * amount of workstations and list:
    SD_task_get_workstation_count(task)
    SD_task_get_workstation_list(task)
