LukesLazyLoader.load is broken (at least in latest version of chrome). The reason is that, since LukesLazyLoader.load explicilty passes two arguments to the LukesLazyLoaderconstructor, the constructor only has access to those two arguments, (when it looks at the arguments variables), as a opposed to a variable number of arguments as you intended.

Thus when you write the following in the docs:

LukesLazyLoader.load('your', 'css', 'and', 'js', 'files').then(callback).then(anotherCallback);

Only 'your' and 'css' will be loaded. The following three arguments are ignored.
