/**
 * Implementation of {@link org.jasig.cas.authentication.principal.Principal} which encapsulates an <i>Account</i>
 * entity's data from Stormpath cloud IAM provider. This principal gets resolved after a successful authentication against Stormpath.
 * <p/>
 * This implementation encapsulates transformation of Stormpath <i>Account</i> properties into a publicly exposed
 * <code>Map</code> of attributes.
 * <p/>
 * Note that because Stormpath <i>Account</i>s are strongly-typed (in terms of the data they expose), there is no need
 * for a separate complex implementation of <code>IPersonAttributeDao</code> to separately query for attributes. All the
 * necessary attributes will be available in the <i>Account</i> instance made available to this class.
