Detailed Description

The Constellation class models a grouping of stars in a Sky Culture. Each Constellation consists of a list of stars identified by their abbreviation and Hipparcos catalogue numbers (taken from file: constellationship.fab), another entry in file constellation_names.eng.fab with the defining abbreviated name, nativeName, and translatable englishName (translation goes into nameI18), boundary shape from file constellation_boundaries.dat and an (optional) artistic pictorial representation. GZ NEW: The nativeName should be accessible in a GUI option, so that e.g. original names as written in a concrete book where a skyculture has been taken from can be assured even when translation is available. TODO: There should be a distinction between constellations and asterisms, which are "inofficial" figures within a sky culture. For example, Western sky culture has a "Big Dipper", "Coathanger", etc. These would be nice to see, but in different style.
