// Define an empty object to store callbacks that are used to retrieve custom attributes
// The simplest example for a custom attribute is the Timepoint type (i.e. baseline or follow-up)
// used in the LesionTracker application.
//
// Timepoint type can be obtained given a studyId, and this is done through a custom callback.
// Developers can define attributes (i.e. attributeId = timepointType) with a name ('Timepoint Type')
// and a callback function that is used to calculate them.
//
// The input to the callback, which is called during viewport-image matching rule evaluation
// is the set of attributes that contains the specified attribute. In our example, timepointType is
// linked to the study attributes, and so the inputs to the callback is an object containing
// the study attributes.
