#luvit-set Straightforward Lua Set library for Luvit

##Install

• Download and install Node.js. Then you have npm
• In the root of your Luvit project, npm install luvit-set

##Usage Start off with

local Set = require("luvit-set")

Then, to create a set (of things you like):

local ilike = Set:new()

to add items to a set:

ilike:add("apples")
ilike:add("bananas")

or, initialise with values on creation:

local ilike = Set:new({"apples", "bananas"})

Let's create another set:

local ulike = Set:new({"apples", "strawberries"})

Then we can:

local welike     = ilike + ulike -- union:        apples, bananas, strawberries
local webothlike = ilike * ulike -- intersection: apples
local udontlike  = ilike - ulike -- subtraction:  bananas

Lastly, some conveniences:

local somethingilike = ilike:anelement()
ilike:len()  -- 2
for k, _ in pairs(ilike) do
  print(k)
end
print(ilike) -- '{"apples", "bananas"}'
local list = ilike:tolist() -- {"apples", "bananas"}
