Migrating excel module out of the Zorba core
Changes on tests spec files to fit with the changes in the ErrorHandling
Fixed error in which build was uploaded
Fixed test
Use PROJECT_SOURCE_DIR; set all eol-style to "native".
updated example tags in the modules.
Added namespace declaration for math in excel/statistical-zorba
I have added the correct categories for the modules that appear as part of the left menu tree of the XQDoc documentation. I have also update the external modules as well.
ZORBA_WITH_BIG_INTEGER is now OFF by default.
XQDoc rework.
Now zorba and each external module have two build targets: xqdoc-xml and xqdoc. 
xqdoc-xml is to generate the xml from xqdoc information.
xqdoc target is to generate the final html from the intermediary xml.
Zorba's xqdoc depends on the xqdoc-xml from zorba and all external modules.
You can also build the xqdoc target for a specific external module, and generate only its documentation. If the external module is built in zorba project, then the zorba internal modules' xqdoc is always generated.
- fix pretty printing of annotations in the function description (don't print non-deterministic but %nondeterministic):FIXED
- some schemas don't show up as links:FIXED
- put a code snippet in the header of every module that tells you how to import the module (i.e. import module namespace). This is useful for copy and paste.:FIXED
- the symbol indicating that a function is external appears in a column on the right-hand side. This column should be merged with the first column, i.e. all images should appear in the first column.:FIXED
- put a tiny icon in the module outline and the header of each module to show whether the module belongs to the core:FIXED
- the generated XQDoc XML's are now valid according to the XQDoc Schema (the information needed by Zorba is saved in a different XML part of the /config folder)
This should be saved in the same manifest files created during the module compilation process.:FIXED
- Variables are listed without the $ and without the prefix for the module (for usability the documentation should show them  *exactly* the way  users use them..): FIXED
new DECLARE_ZORBA_MODULE macro for all external modules + version 1.0 for all modules
Fix for bug #3348874
Added DECLARE_ZORBA_SCHEMA() and cut over internal and external modules to
use it. Enhancements to DECLARE_ZORBA_MODULE(), including better API with
explicit parameters, and shorter target names to help Windows 260-character
path limitations.
Moved non-W3C annotations to the Zorba namespace. Unknown annotations will raise errors.
Restructure DECLARE_ZORBA_MODULE()/DECLARE_ZORBA_SCHEMA() to not create a ton
of mini-targets, to help clean up MSVC projects. Required introduction of
DONE_DECLARING_ZORBA_URIS() which is added to all module projects and Zorba.
Removing stale INSTALL directives from external modules.
XQuery version changes:
- Added XQuery version declarations for all the modules (part of the Zorba core or not).
- fixed the test "moduleDocumentation" that checks if all the modules are well documented:
  - this test used to check only the Zorba core modules: now it also checks the external modules.
  - added a new rule that makes sure all modules have a XQuery version declarations.

XQDoc changes:
- documented some XQDoc variables, params and return values that were missing.
- added support for XQuery version and Encoding in the Zorba XQDoc.
- added a new part called "XQuery version and Encoding for this module:" as the last lines in the module description of the XQDoc documentation.
Adding a automatic test case for each declared module which imports the module,
to ensure it compiles and can be imported. Fixed several bugs which were
revealed by those tests. Also, changed variable ZORBA_EXE_SCRIPT to
ZORBA_EXE and made this variable available in ZorbaConfig for other projects.
- improved the speed of "make xqdoc" such that we can add xqdoc as a test
- fixed SF bug #3375604 "Built target cxxdocs" hangs
- make xqdoc does not search the filesystem, instead creates the documentation *only* for the modules that are compiled in the Zorba version used (based on the ZorbaManifest.xml in the build folder)
- implemented the 2 issues that Dana asked for in the email from @coders "core and non-core Zorba modules"
- fixed the link crawler issues in XQDoc reported by Daniel (except the link to xqdoc.org)
