    /**
     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array and iteratees accept only
     * one argument. The heuristic for whether a section qualifies for shortcut
     * fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:
     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
     * `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
     * `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
     * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,

// 用户在绘图区通过拖拉拽调整了兄弟节点信息之后, 能同步到自适应参数里面来

/*
自定规则(2019-10-10调整V4)
1. 对栅格的兄弟节点及其子孙节点有效
2. 如果新进来的控件有自己的属性,且不可以自己调整时不做处理(如果有固定属性,但是允许调整会走到我们的规则)
3. 如果兄弟节点没有关联栅格,则不再继续往下走
4. 如果关联的栅格不是artboard当前显示的栅格(artboard中没有,或者有但是当前没有显示),则拖拉拽不会切到栅格单位, 如果之前是栅格单位则会切换为dp单位
5. 如果是关联到分栏栅格, 则左边的栅格的图层不能向右出分界线, 右边的图层不能向左处分界先, 如果超出则强行拉回, 其他情况图层均可以跑出artboard
6. 如果上下边距都是0则,无论原来是什么都改为上下0,高度auto
   如果上边距为0,下边距不为0, 则调整为 上+高或单上(全局开关控制高度是否需要), 下边距为auto
   如果上边距不为0,下边距为0, 则调整为 下+高或单下(全局开关控制高度是否需要), 下边距为auto
   其他情况,沿用原来的方位参数
   所有单位和原来保持一致,不自动切换(默认单位为dp)

7. 画板无栅格或者图层隶属的栅格和当前的画板的栅格不一致时 -- 不受栅格控制
  如果左边距为0,且右边距为0, 无论原来是什么都改成左右边距为0, 宽度为auto,左右边距中如果有栅格为单位的,则切换为dp, 否则沿用原单位
  如果左边距为0,且右边距不为0, 则调整为 左+宽或单左(全局开关控制宽度是否需要), 右边距为auto, 非auto的方位如果之前的单位为栅格,则切换为dp, 否则沿用原单位
  如果左边距不为0,且右边距为0, 则调整为 右+宽或单右(全局开关控制宽度是否需要), 左边距为auto, 非auto的方位如果之前的单位为栅格,则切换为dp, 否则沿用原单位
  其他情况,沿用原来的方位参数
  非auto参数的单位如果为栅格, 则切换为dp, 其他情况沿用原单位

8. 画板有栅格或者图层隶属的栅格和当前的画板的栅格一致时 -- 栅格控制介入
  如果左边落在有效的栅格热区, 则宽度受栅格控制
    左边会自动吸附对齐到栅格,同时右边会对齐到栅格,单位就会变为栅格
    如果原来是左+宽, 方位: 左+宽
    如果原来是右+宽, 方位: 右+宽
    如果原来是左+右, 方位: 左+右
    如果原来是单右,  方位: 右+宽
    如果原来是单左,  方位: 左+宽
    如果原来是单宽,  方位: 左+宽
    如果原来是全部auto, 方位: 左+宽
  如果左边落在有效的栅格热区, 则宽度不受栅格控制
    不受控时逻辑和第7点无栅格时的逻辑一致

监听的action为:
    1.LayersResized.finish
    2.LayersMoved.finish

提供一个全局开关来控制是否开启自适应参数是否反向同步
