Indeed web scrapping for KSAs

This a fairly simple web scrapping solution. It saves job ads from
indeed.com as text files and then, for
each job ad a search for sentences is performed and saved.
After collecting the sentences, the report looks for keywords
identified around knowledge skills and abilities (KSA's).
The code is written in R version 3.5.1 (2018-07-02),
using packages listed in 00_installPkgs.R,
developed on a x86_64-pc-linux-gnu platform.
