/**

|
|
* Creates a new object by recursively evolving a shallow copy of `object`,
|
||
|
|
* according to the `transformation` functions. All non-primitive properties
|
||
|
|
* are copied by reference.
|
||
|
|
*
|
||
|
|
* A `transformation` function will not be invoked if its corresponding key
|
||
|
|
* does not exist in the evolved object.

* @param {Object} transformations The object specifying transformation functions to apply
