| /** |
| * A generic Product Crawler for Products. The Crawler is given a root Product |
| * Path and it searches through all directories and sub-directories for .met |
| * files, which it uses to determine products to ingest into the file manger. |
| * The important .met file fields that this crawler requires are: |
| * |
| * <ul> |
| * <li><code>FileLocation</code>: directory absolute path to location of product |
| * file</li> |
| * <li><code>Filename</code>: name of the product file to ingest</li> |
| * <li><code>ProductType</code>: the ProductType that will be sent to the file |
| * manager for the product file described by the .met file.</li> |
| * </ul> |
