// This service is used for in-game purchases.  Most of the actual work occurs in a lua script on player's clients, 
// but this service is responsible for sending the appropriate signals around, and exposing a lua call to our users.
// There is also a nifty function exposed called "GetProductInfo" that will return a table from the web with properties about an assetId
