My in-progress code to implement quicksort in C++ for sorting a CSV file, utilizing multiple threads, to practice working with threads and file I/O in C++
-run the "make" command -format for running the program: quicksorter src-file dest-file "columns to sort by" #threads ex) quicksorter x.csv y.csv "1,0" 2 would sort x.csv with 2 threads and write results to y.csv, sorting by column 1 then column 0
