/**
 * Represents a BaasBox document.
 * <p>
 * A document is a schema less JSON like entity that belongs to a given collection on the server.
 * </p>
 * <p>
 * Documents can be created, stored and retrieved from the server, either synchronously or asynchronously,
 * through the provided methods.
 * </p>
 * <p>
 * Unlike a raw JSON document, some key names at the top level are reserved: you cannot assign or create properties whose names begin with
 * an underscore or an at sign, the <em>id</em> field is also reserved.
 * </p>
 * <p>
 * When a document is bound to an entity on the server it's 'id' can be retrieved through {@link #getId()}.
 * Documents are versioned by BaasBox and updates with incompatible versions will fail, uless you ignore the
 * versioning explicitly through {@link com.baasbox.android.SaveMode#IGNORE_VERSION}.
