Implemented a simple version of the EventBoard, to get things moving.
This implementation should be decoupled later from the DataService, by using a 
BlockingQueue between them and "QueueWorkers" for processing the incomming 
events.

removed in the future so that the usage is transparent for the framework user.

each file. From here ( http://www.gnu.org/licenses/gpl-howto.html ) It seems 
that "Copyright" should include the year of the release and all the people who 
have edited the file.

- Changes to "xslt transformer" are related to: new nterface, file name and a 
few minor changes.
- Added "org.edtf.etsm.functions" which will contain XSLT extension functions 
from etsm.
- Added "call-adapter" extension function skeleton: currently doing nothing 
more than printing a text.

- Intermediary check-in for an "application wide" component container, 
configurable using edtf.components.xml. This is behaving  like a configurable 
object factory. This can allow, in the future, plug-in based extensions of 
things like EventBoards, ComponentMappers, XML extensions, etc.

- Added EventManager, which will be a "proxy" (for EventIO and 
core.etsm.functions), by managing access to the EventBoard and it's events.
- Added a first implementation of the "catch" - far from the final version 
(especially in design).
- Small refactoring on a couple of components

- Added more code for the catch extension. A message can be posted and catched 
(in a non-blocking way) successfully. However, the catch implementation is 
still far away from the standard requirements.
- Added fixes for a couple of components, including Event, EventManager, 
EventBoard.
- Refactored how namespaces are handled inside the XPathAdapter. The same 
should follow for the XSLTAdapter later.

- Added date convertion (from xsd:dateTime to Java Date) interface & 
implementation. It is not feasible, at least now, to include a 3rd party 
library only for date conversions. So these can be abstracted from the XSLT 
engine quite easily.

- Added Scriplet, which now runs as a separate thread and using its own 
transformer instance (both for "sync" and "async" scriplets). Currently each 
scriplet is transformed and executed only when it's needed - this adds some 
complexity when it comes to reffering to "global" variables defined in the 
execution context. Under the hood this can be perhaps implemented using 
"implicit" parameters that are passed in the same way as the scriplet 
parameters passed explicitely using withParam.
Scriplet parameter passing is currently missing.

- First transformation is working using xtemp, but without "global variables". 
Still some work for the second transformation. Need to recheck the use cases 
for the catch operator.

 - Adjusted the EventBoard.query() so that it can be stopped using stopCatchingEvents().
   - This is still a limited implementation which should be extended in a future iteration (see comments).
 - ExecutionContext is searching for EventBoards only in the /execution-context (the default event board from the configuration file has been removed).
 - Removed the "definition" suffix from the xtemp.functions.* files.

- A few fixes have been made in order for an Event to be inserted into the 
EventBoard. However, there is an issue when catching events (see below).
  - XTemp translator looks at some point for /event-board/events/event[1], but we store individual events as NodeInfo & XML (i.e. not the entire EventBoard as XML) so that a query is performed directly on the NodeInfo, without rebuilding the tree for each query.
  - A solution might be to look for a way to keep the entire EventBoard as a single NodeInfo and perform queries on that node. However, I don't have numbers about the overall performance (query, update, ..) of the two cases (i.e. keeping the entire EventBoard as a NodeInfo or having EventBoard as a list of Events which contain a NodeInfo). Having the EventBoard as a single NodeInfo might favor query operations performance while perhaps degrading update operations performance.
  - A load-test & benchmark should be made after edtf v0.1 is released for accurately measuring the performance of the two design approaches.
    - Perhaps having both implementations is also a practical approach, so that users who have lots of queries will choose one configuration. Anyway, this design decision can be easily refined after v0.1 (changes being isolated in the EventBoard implementation).
- Refactoring: Config is no longer a singleton, being a normal instance which 
is used by the ExecutionContext. (TODO: The same will be done for EventManager 
and EventBoardManager singletons).
- Refactoring: XPathSaxon no longer contains some hard-coded name-spaces, 
imposed by the usage of this class in the Config class (which should read the 
name-spaces from the XML configuration file). The remaining ones will be 
removed in the next iteration (see comments about why/how this is achieved).

- Migrated to netbeans 7.0.1.
- XTemp translator: Added proper escaping for the extension function arguments.
- Removed functions.xsl, as we aim for only one deployment scenario. And that 
is the one in which events are inserted into the framework through the 
web-service interface. For the "classic mode" (in which events are stored 
inside a file) the original XTemp translator can be used.
- Added a few unit tests for the Configuration component. More tests have to be 
added in the next period.

- XTemp translator: Inside <catch>, store the "current event" in a variable. 
Otherwise the "@timestamp" and "@id" queries will generate "XPTY0020: ... the 
context item is an atomic value" errors.
- QueryBoard: return type changed to SINGLE_NODE.
