incremental backup of grasps

[jon-weisz]

The experiment manager should pull the grasps out of the database and store them to disk as the experiment progresses.

It should also be able to recall grasps from old experiments and push them to the server

experiment_manager should get an experiment_name member Then it should generate file names for each generation like

def get_grasp_file(generationnumber): return "%s%i_grasps.backup'%(self.experiment_name, generation_number)

Then

backup_grasps(generation): self.interface.incremental_backup(self.get_grasp_file(generation), ['Grasp']) self.interface.clear_grasp_table()

restore_grasps(generation): self.interface.incremental_restore(self.get_grasp_file(generation), ['Grasp'])
