# merge(o, a, b) -> c

3-way merging of JavaScript objects

Takes 3 versions of the same object -- where version 2 and 3 are both derived from version 1 --
and generates a 4th version, effectively merging version 2 and 3 together. When a conflict is
detected (changes made in both version 2 and 3) changes from version 3 are used.

## Prototype

    merge(Object original, Object current, Object new) -> Object

- `original`: Ancestor version (original) from which both `versionA` and `versionB` are derived

- `current`: Version A of `original`

- `new`: Version B of `original`

## Example:

    // The original version which both A and B are derived from
    original = {
        aliases: {
            abc: "Abc"
        },
        deleted: 7890,
        key: "string",
        list: [
            "abc",
            "def"
        ],
        value: 1234
    }

    // Version A
    current = {
        aliases: {
            "abc": "Abcdef",
            "def": "Def"
        },
        list: [
            "abc",
            "cat",
            "def",
            "xyz"
        ],
        value: 123456
    }

    // Version B
    B = {
        aliases: {
            abc: "Abc",
            aab: "Aab"
        },
        list: [
            "abc",
            "zzz"
        ],
        value: 1234
    }

    // --> Merged result
    {
        aliases: {
            abc: "Abcdef",
            aab: "Aab",
            def: "Def"
        },
        list: [
            "abc",
            "cat",
            "xyz",
            "zzz"
        ],
        value: 123456
    }

## Requirements

- `Array.isArray(object) -> Boolean` to be implemented (which it is already in modern JavaScript environments)
