f17ce28b6d *) plasmaHTCache:
- method loadResourceContent defined as deprecated. 
     Please do not use this function to avoid OutOfMemory Exceptions 
     when loading large files
   - new function getResourceContentStream to get an inputstream of a cache file
   - new function getResourceContentLength to get the size of a cached file
*) httpc.java:
   - Bugfix: resource content was loaded into memory even if this was not requested
*) Crawler:
   - new option to hold loaded resource content in memory
   - adding option to use the worker class without the worker pool 
     (needed by the snippet fetcher)
*) plasmaSnippetCache
   - snippet loader does not use a crawl-worker from pool but uses
     a newly created instance to avoid blocking by normal crawling
     activity.
   - now operates on streams instead of byte arrays to avoid OutOfMemory 
     Exceptions when operating on large files 
   - snippet loader now forces the crawl-worker to keep the loaded
     resource in memory to avoid IO 
*) plasmaCondenser: adding new function getWords that can directly operate on input streams
*) Parsers
   - keep resource in memory whenever possible (to avoid IO)
   - when parsing from stream the content length must be passed to the parser function now.
     this length value is needed by the parsers to decide if the parsed resource content is to large
     to hold it in memory and must be stored to file 
   - AbstractParser.java: new function to pass the contentLength of a resource to the parsers

ab5a9bee66 *) adding some copyright headers
*) next step of restructuring for new crawlers
   - adding first testversion of ftp crawler class
   -- does not create a htCache entry yet

4e2a950ac9 *) next step of restructuring for new crawlers
- avoid using the http crawler class directly. Using the interface class instead

09b106eb04 *) next step of restructuring for new crawlers
- adding interface class (plasma/crawler/plasmaCrawlWorker.java) for protocol specific crawl-worker threads 
   - moving reusable code into abstract crawl-worker class AbstractCrawlWorker.java
   - the load method of the worker threads should not be called directly anymore (e.g. by the snippet fetcher)
     to crawl a page and wait for the result use function plasmaCrawlLoader.loadSync([...])

eb9b138986 *) next step of restructuring for new crawlers
- conversion of the crawler pool into a keyed object pool
   - crawlers are now loaded based on the url protocol (of course works only for http now)
