Began the process of generalising the transition routine so that I can
use it to move the stars into scatter plots
Removed all of the old transition code.  Updated index.html to reflect
variable name changes.
Added new modules Stellarum::Words and Stellarum::Stars.
Checked in changes to Wikifiles and the new wiki_stars.pl script, plus a
bunch of incidental changes.
First draft of refactored wiki_stars.pl - works OK but doesn't do any extra
fields
Merge branch 'master' of https://github.com/spikelynch/stellarum into visualisations
Beginnings of stellar database search
Added executable mode to sd_stars.pl
First near-successful wiki_stars.pl that pulls out multiple stars
Added code to read a combined database from three catalogues and match
parameters from them.
Cleaned up a lot of old files
Latest versions of the three collation scripts
Moved CSV files into their own directory, cleaned up obsolete ones
Latest version of starmap and stars.js
Latest versions of Perl libraries
Renamed the collation scripts so that their names mean something.
get_wiki_parameters fixed to used the streamlined stars_from_tweets function
and no longer bothers grepping out parameters for multiple star systems, as
we're leaving that to the Hipparcos data
Moved CSV -> Data
First working version of the parameter scatter-plot feature.  Still a bit
rough around the edges and there are a handful of stars which need parameters
added by hand.
Interpolations are working from plot back to celestial sphere
Tidied up some issues with the plot axes - increasing brightness now maps
onto -> right and up, and the RA is the same way up as the celestial sphere
(south at the top)
