Refactored Docs generation so it doesn't read/write to disk - MUCH faster.
Renamed all 'code' folders to 'z_code' so that they appear beneath their markdown sections when sorted alphabetically
Included Globule package, to generate docs file list as array of strings
Renamed 'config' variable to 'languages'
Split the Cheerio function out into its own 'containContent' function
NOTE: gulp-size, gulp-tap, gulp-debug and gulp-filelog are all very valuable for debugging
