new feature about input array

[chaz1942]

when you input {foo:[1,2,3]},you will get 123,not 123. about eBay API interface many tabs are using same tab names.

e.g.
<PictureDetails>
    <PictureURL>picture url</PictureURL>
    <PictureURL>picture url</PictureURL>
    <PictureURL>picture url</PictureURL>
</PictureDetails>

current version cannnot provide feature like this, its output 123
