@joshbmarshall Is it possible to get this merged in? Need it for a client project I'm working on :)

Hi Joel, thanks for the pull request. Unfortunately there were a number of issues:

• The file was reformatted, causing a number of unnecessary line changes and made the file out of line with the rest of the code base
• The variable name used camelCase while the rest of the variables did not. So uniformity was lost.
• The parcels variable is defined as an empty array, so no need to check whether it is an array. Also no need to count them, as iterating over an empty array does not execute anything inside.

What I've done is recreate your pull request with the necessary changes and released the code. Please confirm this suits your needs!

Sorry if it sounds like I'm being picky, but I'm trying to keep it as clean as possible.
