/**
* Creates a shallow clone of the passed object by applying an `fn` function
* to the value at the given path.
*
* The function will not be invoked, and the object will not change
* if its corresponding path does not exist in the object.
* All non-primitive properties are copied to the new object by reference.
*
* @func
* @memberOf R
* @category Object
* @sig [Idx] -> (v -> v) -> {k: v} -> {k: v}
* @param {Array} path The path to be modified.
* @param {Function} fn The function to apply to the path.
* @param {Object} object The object to be transformed.
* @return {Object} The transformed object.
* @example
*
* const person = {name: 'James', address: { zipCode: '90216' }};
* R.modifyPath(['address', 'zipCode'], R.reverse, person); //=> {name: 'James', address: { zipCode: '61209' }}
*
* // Can handle arrays too
* const person = {name: 'James', addresses: [{ zipCode: '90216' }]};
* R.modifyPath(['addresses', 0, 'zipCode'], R.reverse, person); //=> {name: 'James', addresses: [{ zipCode: '61209' }]}
