Fix shallowClone

John Haley · John Haley · commit 4a2d1892b143 · 2015-08-06T15:34:48.000-07:00
`shallowClone` was expecting an additional object as the first parameter on which
it would then place the keys for all objects passed into the function. Now it just creates
that object internally and returns that value.
