LuaZip: Reading files inside zip files

LuaZip
Reading files inside zip files

## Example

Suppose we have the following file hierarchy:

    /a
        /b
            c.zip
    /a2
        b2.ext2
    /a3.ext3
    /luazip.zip

- c.zip contains the file 'd.txt'
- b2.ext2 is a zip file containing the file 'c2/d2.txt'
- a3.ext3 is a zip file containing the file 'b3/c3/d3.txt'
- luazip.zip contains the files 'luazip.h', 'luazip.c', 'Makefile', 'README'

Below is a small sample code displaying the basic use of the library.

    require "zip"

    local zfile, err = zip.open('luazip.zip')

    -- print the filenames of the files inside the zip
    for file in zfile:files() do
    	print(file.filename)
    end

    -- open README and print it
    local f1, err = zfile:open('README')
    local s1 = f1:read("*a")
    print(s1)

    f1:close()
    zfile:close()

    -- open d.txt inside c.zip
    local d, err = zip.openfile('a/b/c/d.txt')
    assert(d, err)
    d:close()

    -- open d2.txt inside b2.ext2
    local d2, err = zip.openfile('a2/b2/c2/d2.txt', "ext2")
    assert(d2, err)
    d2:close()

    -- open d3.txt inside a3.ext3
    local d3, err = zip.openfile('a3/b3/c3/d3.txt', {"ext2", "ext3"})
    assert(d3, err)
    d3:close()
