CSV parser for Lua

Examples:

Reading CSV data:

local CSV = require 'csv'
local d = CSV.file(filename)	-- read data from file
local d = CSV.string(string)	-- read data from string

Accessing data by row/column indexes:

print(d.rows[i])	-- access the i'th row
print(d.rows[i][j])	-- access the j'th column of the i'th row

Accessing data by named columns:

local names = {'id', 'rank', 'etc'}
d:setColumnNames(names) -- sets column names, then you can do this:
d.rows[1].rank			-- gets you cell 1,1

Setting field names to the first comment line:

local string = require 'ext.string'
d:setColumnNames(string.split(d.comments[1],','))

Setting field names to the first row:

d:setColumnNames(d.rows:remove(1))
