Usage

// Requiring the module
var imageGalModule = require('image-gal');

// Instantiation
var imageGal = imageGalModule()

// Using own template file
var template = 'my-template.html'

var imageGal = imageGalModule(template);

Then you can use it as an Express.js route handler

app.get('/images*', imgGal);

If the url path is /images it will output images folder contents if the url path is /images/cats it will output cats folder contents

If you use your own template file put <% images %> where you want images' html to appear
