Default init path to CWD (like NPM init)

[FokkeZB]

Currently if you leave out the path it neither refuses to run nor complete successfully. It should do either, and my suggestion is to default to the current working directory, like npm init does.

MacBook-Pro-van-Fokke:swagger fokkezb$ zapier init
Initializes a new Zapier app in a directory.

Usage: `zapier init path`

Initializes a new Zapier app. If you specify a template, will download and install the app from that template.

After running this, you'll have a new example app in your directory. If you re-run this command on an existing directory it will leave existing files alone and not clobber them.

> Note: this doesn't register or deploy the app with Zapier - try zapier register "Example" and zapier push for that!

**Arguments**

* location [value] -- **required**,
* --template={minimal,resource,trigger,create,search,middleware,basic-auth,custom-auth,oauth2,session-auth,babel} -- _optional_, select a starting app template. Default is minimal

$ zapier init example-app --template=minimal

I'm not a huge fan of this - as it could clobber your working directory. npm has a lot of "inbuilt" knowledge of it being used in the working directory. Compare that to pip which is all about the current virtualenv (and doesn't care at all about working directory).

[FokkeZB]

Still I think since these apps are NodeJS and even more because the command is "init" (not "create") it makes sense to follow existing patterns in that ecosystem.

But if we don't, then at least the command should fail right away IMHO since with this much output before the error, it's easy to miss - in particular in a B/W console.

[bryanhelmig]

I am really uncomfortable with the level of setup we do (creating files, folders, etc.) without an explicit location argument.

Maybe we don't print help right away but suggest it? Definitely cluttered as is and hides the error message.

[FokkeZB]

Let's clean it up then, since in particular the last line of help is confusing if it's printed just before the error. You could think it actually did finish:

# Finished! You might need to npm install then try zapier test!

I'd prefer:

$ zapier init
Error: Missing required argument 'path'

Run `zapier help init` for usage.
