Box3 class use different logical operator for point and box object

Hi, I hope you guys stay safe.

There is one simple thing I hope to discuss with you.
Box3 class has a function to check if Box3 contains a box,

``` containsBox( box ) { return this.min.x <= box.min.x && box.max.x <= this.max.x && this.min.y <= box.min.y && box.max.y <= this.max.y && this.min.z <= box.min.z && box.max.z <= this.max.z; } ```

,and also has a function to check if Box3 contains a point, but it use different logical operator, ` || ` so this method actually trying to check if the point is outside the Box3.

``` containsPoint( point ) { return point.x < this.min.x || point.x > this.max.x || point.y < this.min.y || point.y > this.max.y || point.z < this.min.z || point.z > this.max.z ? false : true; ```

```} ```

Of course, the method works correctly as it returns `false` if the point is outside of the Box3, however using `&&` may seems to be easier to understand at a glance and maybe it could be more consistent with `containsBox( box )` method imao.

``` containsPoint( point ) { return this.min.x <= point.min.x && point.max.x <= this.max.x && this.min.y <= point.min.y && point.max.y <= this.max.y && this.min.z <= point.min.z && point.max.z <= this.max.z; } ```
