Is the type of the "exclude" element in project.json string or array?

According to this wiki, https://github.com/aspnet/Home/wiki/Project.json-file, the type of the exclude element is string. But it actually it supports both of array and string. And, when we can specifiy multiple items like
1)
"exclude": [ "Controllers/.cs", "Dispatcher/.cs", "Filters/.cs", "Formatting/.cs",
"Http/.cs", "MessageHandlers/.cs", "Model/.cs", "ModelBinding/.cs"]
or
2) "exclude": "Controllers/.cs;Dispatcher/.cs;Filters/.cs;Formatting/.cs;Http/.cs;MessageHandlers/.cs;Model/.cs;ModelBinding/.cs;"

I think it could be a bit confusing if one element supports both types. (VS reports a warning when array is used for the exclude element, but kre builds this without any problem.)

If we want to pick one of the type, I think it should be array instead of string; array is clearer than string when specifying mutlple items to exclude.

+1 for an array because it can span multiple lines.

We had strings originally and added support for arrays. I'm fine removing the string support.

/CC @madskristensen - project.json intellisense needs to be updated for this.
