RShiny vis of analysis tools for life scientists

[npscience]

@bjw49
[x] create interactive visualisation of the 'analysis tools that life scientists use' data
Files needed are at https://github.com/npscience/open-research-doathon

...count.csv
master.R --> RShiny app (thanks to @bjw49 :D)
Remaining tweaks for the Shiny:
[x] order bars by highest count first (native order in the csv); currently alphabetical
[] transpose x<-->y so that tool names are on y-axis
[] select roles to display as grouped bars (e.g. show all, PhD and professor bars)
