+ * Lottie Animation is a modern style vector based animation design. Its animation
+ * resource(within json format) could be generated by Adobe After Effect using
+ * bodymovin plugin. You can find a good examples in Lottie Community which
+ * shares many free resources(see: www.lottiefiles.com).
+ *
+ * This Lottie_Animation is a common engine to manipulate, control Lottie
+ * Animation from the Lottie resource - json file. It provides a scene-graph
+ * node tree per frames by user demand as well as rasterized frame images.
