npm init command should use the directory name instead of "index.js" as the default main entry point.

The main reason is that the nodejs module.children and require objects use the full path of the module entry point as properties. It is more convenient to see and use this as the module name too.
I believe it will encourage proper usage practice in newcomers as well.

In the ```npm init`` command below the (index.js) should be (example_module) instead.

package name: (example_module)
version: (1.0.0)
description:
entry point: (index.js)   <-- this should be (example_module)
