Title: Added functions "read_all" and "get_header" in lib/csv.nit

Added these functions to lib/csv.nit

read_all enables to read all lines from an existing csv file and returns
them in a String.

get_header enables to get the header (actually the first line) from an existing csv file and returns it in a String.
