Initial

Committing initial files, today's work mostly have the basics, will
build on from here.
Updates for video overlay, animated stats, css

Style sheet isn't picking up some elements added on the fly, will debug
later. beatPregnant.tsv is a tab-separated file with the stats that D3
reads. Easy to add other countries' stats as found. Added youtube
overlay on the SVG to play "one billion rising" video -- a generic or
country-specific.
Lots of wasted code and lack of optimization. Really need to clean this
up, a little embarrassed by it, but it's getting the job done. Would be
helpful to lookup some D3 calls and learn D3 better rather than rely on
jQuery.
tooltips for Canvas data display changes

Switched out tooltips in favor of Canvas data display (scrolling at top
of screen -- still need to fix re: size of video window).
