/**
 * @module ReplicationSummaryCard
 * The `ReplicationSummaryCard` is a card-like component.  It displays cluster mode details for both DR and Performance
 *
 * @example
 * ```js
 * <ReplicationSummaryCard
    @title='States'
    @replicationDetails={DS.Model.replicationDetailsSummary}
    />
 * ```
 * @param {String} [title=null] - The title to be displayed on the top left corner of the card.
 * @param {Object} replicationDetails=null - An Ember data object computed off the Ember Model.  It combines the Model.dr and Model.performance objects into one and contains details specific to the mode replication.
