Ensure that the argument is an array by wrapping it in an array if it is not.
Creates a copy of the argument if it is already an array.

This is mostly useful idiomatically:

  var createArrayFromMixed = require('createArrayFromMixed');

  function takesOneOrMoreThings(things) {
    things = createArrayFromMixed(things);
    ...
  }

This allows you to treat `things' as an array, but accept scalars in the API.

If you need to convert an array-like object, like `arguments`, into an array
use toArray instead.

@param {*} obj
@return {array}
