FLUID-4826: Re-construct the use of the interval event conductor component.
FLUID-4826: Make interval event conductor and transcript components the child components of video player rather than the media component. Having errors at rendering transcript component.
FLUID-4826: More progress on interval conductor reconstruction. Having issues with setting interval list into conductor when the transcript is loaded.
FLUID-4826: The first completed version of the re-constructed video player on interval conductor and transcript.
FLUID-4826: Fixed the unit tests for interval event conductor and transcript that are broken by the reconstruction.
FLUID-4826: Code clean-up.
FLUID-4826: Code clean-up as well as adding comments according to feedbacks from the code review.
FLUID-4826: Fixed the video player integration.
