Consideration of XRT Level0 Quick Look web service.
22-Mar-2017, Aki Takeda.
1. Creation of XRT level0 QL web service.
1.1 Motivation.
Started from Chunming Zhu's personal products (movies of all XRT data).
It would be benefitial to provide easy quick-look service for general
users of XRT data: Users can check the availability of XRT data
before downloading the actual data for analysis.
1.2 What is the desirable features as the QL archive ?
Monthly movie files for each analysis filter and exposure time (?).
Mpeg(light) v.s. Javascript(can move forward/back by single image).
Exclude dark frames, G-band images, Flare monitor images(Ti-poly 8x8).
