A small change to keep your contributions safe

[Kim Dykeman]

Hi folks,

Just a heads up, we're planning on bringing license_finder into alignment with Pivotal policy which requires that each contributor do a one-time click through a Contributor License Agreement (CLA) before we accept new pull requests that aren't obvious fixes. The policy is meant to protect you as a contributor as well as Pivotal and its users - it isn't meant to be restrictive. The Individual and Corporate CLAs can be found at https://cla.pivotal.io/. To keep friction to a minimum, we'll add a helpful bot to the PR workflow to keep track of the folks who have signed so you only have to click through once.

Your contributions are very much appreciated... Please keep them coming!
