[HiPS] planeto support

[Pierre Fernique]

Dear HiPS users/contributors, dear Europlanet/VESPA members,

We have progressed on HiPS planeto support "exploration" (in the 
framework of VESPA Europlanet european project).
The CDS is pleased to announce:

 1. The extension of the HiPS planeto collection (either based on
    previous FITS conversions (Chiara Marmo/Université-Paris-Sud work)
    or directly from JPEG CAR maps) => 17 HiPS maps and panorama
 2. This collection is now publicly available in Aladin Desktop beta
    ("Planet" branch in the data collection tree - see below).
    => http://aladin.u-strasbg.fr/java/AladinBeta.jnlp
 3. The Aladin Lite support of HiPS planeto (Thomas Boch's development)
    =>
    http://aladin.u-strasbg.fr/AladinLite/doc/API/examples/mars-visualisation/

These tools recognize the *hips_frame* keyword of the HiPS properties 
file. We have extended the supported vocabulary (equatorial, galactic, 
ecliptic => solar, mercury, venus, earth, moon, mars, jupiter, saturn, 
...). If the value is not the 3 celestial coordinate frames, by default, 
the longitude is inverted for the display. Also, by default Aladin 
Desktop chooses a spherical projection (SIN) like Aladin Lite.

These developments are still in test phase
