   PROCESSING CHAINS
    Much of the crawler's work is specified by the sequential 
    application of swappable Processor modules. These Processors
    are collected into three 'chains'. The CandidateChain is applied 
    to URIs being considered for inclusion, before a URI is enqueued
    for collection. The FetchChain is applied to URIs when their 
    turn for collection comes up. The DispositionChain is applied 
    after a URI is fetched and analyzed/link-extracted.
