Added 2008-2010 data

Added 2008-2010 txt data files. Split data.R into data.main.R and
data.01.R to extract data from multiple timespans.
discipline.graph.R for multiple time spans

Split and edited discipline.graph.R to support extraction and plotting
of single-discipline graphs for all time spans.
union.graph.R for multiple time spans

Split and edited union.graph.R to support creation of union graphs for
multiple time spans. Split code for graph plotting into
union.graph.plots.R.
network.video.R

First draft of script to get network video. Edited union.graph.01.R to
only keep main component in the union graph.
Improved network.video.R

Improved network.video.R, added saveHTLM() to export animation, worked
on getting attributes into dynamic network object.
Added graphical parameters to network.video.R

Added code for node size, edge weight and edge color to
network.video.R. Added legend.
Added data from 1996-2007

Added row data from 1996-2007. Edited data.main.R to import them.
Proportional number of authors

Changed the code and organization or .R files so that the number on
social sciences vs comp science/physics authors in the final network is
proportional to the number of cited authors in the social science data
vs comp science/physics data.
1996-2013 networks and animation

Added code for extracting the networks in all time periods, and getting
the complete network animation 1996-2013
1996-2013 networks and animation

Added code for extracting the networks in all time periods, and getting
the complete network animation 1996-2013
Made project reproducible from 00_main.R

Changed file names and initial settings such as setwd() in .R files so
that the whole project can be launched and reproduced from 00_main.R.
Final video settings

Edited network.video.R to tweak the final video settings and the final
ffmpeg command.
Corrected prop authors in discipline.graph.02.R

Corrected the way the number of top authors to keep in each discipline
is determined as a proportion of the total (had forgotten to do a merge
of authors from the 2 disciplines first).
Final static plots

Added script to produce final static plots.
Minor cosmetic edits to .R files

Also added *.rda and /Submission/ to .gitignore.
