Title: Add ability to post process contents

There might be a time when you want to massage the contents being index prior to indexing. For example striping HTML tags. Add a `preprocess` call back option to handle this. The callback will be passed the contents of the file as a string as the forst argument nd the actual file object as the `this` context.
