Correct documentation about request properties

[bbblitz]

Currently, the readme makes the following claims:

Request properties:
path:string however, request.path is a function (that returns a string),
headers:table however, request.headers is a function (that returns a table),
method:function is correct (it's a function that returns a string)
querystring:string however, request.querystring is a table (of strings)
ip:string is correct
port:number is correct

Response properties seem to be all correct.

I found the above with the below script:

local pegasus = require("pegasus")

local server = pegasus:new{
	port="9090",
	location=".",
}

server:start(function(req,res)
	for _,cursor in pairs({req,res}) do
		while cursor ~= nil do
			print("Cursor:",cursor)
			for k,v in pairs(cursor) do
				print("\t",k,":",v)
			end
			cursor = getmetatable(cursor) and getmetatable(cursor).__index or nil
		end
		print("----------------")
	end
end)

Gives the output

Pegasus is up on 0.0.0.0:9090

In case it matters, I'm on Windows with luarocks using mingw32 as my compiler.

I really don't care if you make everything functions that return these things, or make them actual fields, but this inconsistency is really confusing!

@bbblitz I'm not sure if I understood your point.
You don't agree with the fact that we've some properties and some methods, is that?

[bbblitz]

I don't agree that they're documented as properties, but are actually methods (except for querystring:string, which is actually a table)

[EvandroLG]

You're correct, there're some outdated information.
Thanks for letting me know, I didn't notice this issues :)
