Return the CrawlableDataset for the given path, null if this InvDatasetScan
does not allow (filters out) the requested CrawlableDataset.

<p>This method can handle requests for regular datasets and proxy datasets.

@param path the path of the requested CrawlableDataset
@return the CrawlableDataset for the given path or null if the path is not allowed by this InvDatasetScan.
@throws IOException if an I/O error occurs while locating the children datasets.
@throws IllegalArgumentException if the given path is not a descendant of (or the same as) this InvDatasetScan collection level.
Return the CrawlableDataset for the given path null if this InvDatasetScan does not allow ( filters out ) the requested CrawlableDataset .
