content dependency checking

[yongwen]

Different type of contents, such as quests, smartgrid game activities, badges, are inter-dependent. For example, there is a quest, which depends on the completion of an activity called "check-participation". But it is possible that the game designer does not aware the "check-participation" is depended by one of the quest, and did not include the activity in the SGG.

Another example is the Level 4 badge, which depends on the completion of level 4 in the SGG, which implies the level 4 exists in the SGG.

We could think of some kind of content dependency checker, such as SGG checker, only beyond SGG.
