/**
* Base class for handling the required attributes and metrics for monetization
* Events. Currently, AmazonMonetizationEventBuilder is used to create
* monetization events for Amazon purchases, GooglePlayMonetizationEventBuilder
* is used to create monetization events for Google Play purchases and
* VirtualMonetizationEventBuilder is used to create monetization events for
* virtual In-Game Store purchases. This class can be extended if you need to
* record monetization events from other purchase frameworks. Derived classes
* must override the isValid method so that MonetizationEventBuilder knows if
* the derived builder is in a valid state. Derived builders should then call
* the appropriate setters on this class to build a monetization event
* appropriate for their framework. When creating derived classes, the following
* setters must be called on this class or else the builder will return null
*
* - The ProductId must be set
* - The Quantity must be set
* - The Store must be set
* - Either the (Currency and ItemPrice) or the ForrmattedItemPrice must be
* set
