/**
 * Merges the `source` object into the `destination` object. The merge is similar to performing `{ ...destination, ... source }` (where disjoint values from each object would be copied as-is, and for any overlapping props the value from `source` would be used); But for *each prop* (`p`), if **both** `destination` and `source` have a **plain-object** as a value, the value would be taken as the result of recursively deepMerging them (`result.p === deepMerge(destination.p, source.p)`).
 *
 * @param destination - The object to merge into. In general, this object would have it's values overridden.
 * @param source - The object to merge from. In general, shared keys would be taken from this object.
 * @returns The merged object.
 * @signature
 *    R.mergeDeep(destination, source)
 * @example
 *    R.mergeDeep({ foo: 'bar', x: 1 }, { foo: 'baz', y: 2 }) // => { foo: 'baz', x: 1, y: 2 }
