progressionHash property
The hash identifier of the Progression (DestinyProgressionDefinition) that drives whether and when Talent Nodes can be activated on the Grid. Items will have instances of this Progression, and will gain experience that will eventually cause the grid to increase in level. As the grid's level increases, it will cross the threshold where nodes can be activated. See DestinyTalentGridStepDefinition's activation requirements for more information.
