 * Two tasks are compatible if and only if they have the same list of selection script and
 * the same list of node exclusion.
 * The check of compliance is currently done by the {@link SchedulingTaskComparator} class.<br>
 * This method has two side effects : extracted tasks are removed from the bagOfTasks and put in the toFill list
 *
 * @param bagOfTasks the list of tasks form which to extract tasks
 * @param maxResource the limit number of resources that the extraction should not exceed
 * @param toFill the list that will contains the task to schedule at the end. This list must not be null but must be empty.<br>
 * 		  this list will be filled with the n first compatible tasks according that the number of resources needed
 * 		  by these tasks does not exceed the given max resource number.
 * @return the number of nodes needed to start every task present in the 'toFill' argument at the end of the method.
