A simple aspect ratio calculator
While resizing images, use this calculator to preserve their aspect ratio. The formula used by this app is:
(h1 / w1) x w2 = h2
Where h1 is the original height, w1 is the original width, w2 is the new width and h2 is the new height.
Just download the latest release and place the contents of the
bin folder on your local or web server.

Make sure you have Node 0.10^ and npm installed. You'll need to have Grunt and Sass installed. Use these commands:
npm install -g grunt-cli gem install sass
You can then install all the project dependencies using:
Available Grunt tasks:
grunt- will build the whole project.
grunt watch- will watch for any file modifications and will build. Will also build on start.
grunt test- will test the main app js file using
jshint(more tests are coming soon).
For local development you can use
python -m SimpleHTTPServer <specify a port>
and you can check if the build passes using Travis-CI.
