Initial review notes

AcmeSpider is a relatively advanced basic spider that supports multi-threaded usage. The HTML elements that are of interest are reported through a number of callback methods from the HTMLObserver interface, similar to the Swing HTML Parser callbacks.

AcmeSpider also has supporting classes for handling the robot exclusion protocol and specialised URL connection types.
