This command line tool scrapes the list of tasks from Codeforces website (http://www.codeforces.com/). 

Usage: 
	-c  	 	Select task complexity. Ignoring this parameter will result in randomly selected task complexity-wise
	--scrape  	Scrapes data and saves to ./data folder as .csv file. Be sure you have a .csv file unless 
	-p 			Specify a binary executable location (without ./data)
	-d 			Disable browser redirecting to a randomed page

Examples:
	task_randomizer.exe --help
	Get help

	task_randomizer.exe --scrape 
	Must be run first time to get data

	task_randomizer.exe -c B
	Select a random %task%B problem and open in browser

	task_randomizer.exe -c B -d
	Select a random %task%B problem WITHOUT opening in browser
