Must create before increment_counter. Discuss

[pas256]

Currently, if you call increment_counter on an id that doesn't existing in the table yet, the response is:

{
  "status": "error",
  "error_message": "The provided expression refers to an attribute that does not exist in the item",
  "error_code": "ValidationException",
  "error_type": null,
  "raw_response": null,
  "data": null,
  "metadata": null
}

That means you must first call create and give the item a starting number before you can subsequently call increment_counter.

I am thinking it would be nice to handle that inside cruddy. When the above happens, make a subsequent call to create and set the counter_name to whatever the increment is as the initial number.

Thoughts?
