Actual fix to jpeg functionlity
Merge branch 'bug-fixes' into features
Finished implementation of graphics capturing as well as the renaming of snapshot to data within ddg.procedure. Next steps include - supporting more graphic output types and dealing with ddg.snapshot.out and ddg.snapshot
outs.graphic is now changed so that it represents the name of the graphic node to be created after capturing the current graphics device
Small bug fix
