Feature add: Consumption horizon

Consumption Horizon gives your applications visibility into each Member's consumption of the messages in a Channel. The following methods have been added to support Consumption Horizon:

• Consumption horizon additions:

  • function Channel.updateLastConsumedMessageIndex(Number index)
  • int Channel.lastConsumedMessageIndex
  • int Member.lastConsumedMessageIndex
  • Date Member.lastConsumptionTimestamp
  • int Message.index
• API Changes:
• Member#updated will now also fire when Member.lastConsumedMessageIndex is updated.
• Channel#updated will now also fire when Channel.lastConsumedMessageIndex is updated.
• New Channel properties:
• String Channel.createdBy
• Date Channel.dateCreated
• Date Channel.dateUpdated
