--------------------

Add version1 output module: writes out the version number of the used
requirement set to a file.

Output module latex2 is configurable in the way, that it is possible
to give a list of attributes which are printed in the small table
beneath the requirement itself.

Output module graph is configurable: it is possible to specify which
requirement attributes are transposed into node properties.

latex2 output enhancement: comma seperates two requirements - not ends
them.  There is no additional comma at the end of the list anymore.

oopricing1 enhancements: added supplier column, added result sheet,
added version information to file properties.  Removed xml formatting
problem.

graph enhancements: version information was added to the output
graph. 

Utility added which reads in the csv output of the oopricing1 and
converts it into a dependency graph.  Nodes include information about
requirement pricing and dependent pricing.  Also the nodes are colored
after the compliance: green=fully, orange=partial and red=none
compliant.

Fix 3052358: a specific error is logged if a topic does not exists at
all. (This is another case when the requirement is not used because
the topic is not included - in the later case a debug message is
logged, because this is seen as a normal use case.)

Add man page for version1 output.

Add man page for rmtoo-pricing-graph.

Fixed bug which made it possible that a requirement references
itself: self-dependency is excluded now.


Internal Changes
----------------

Blackbox tests comparison enhancement: on different systems /
different times the XML files were stored in different orders.
Therefore all XML files are now parsed and the content is compared -
instead of one seriallized representation.

Changed xml comparison from simple do-it-yourself to xmldiff: the
later one really works in all cases.  The first one had problems when
the nodes are sorted in a different order.  This does not solve the
problem completely: differences are still found where no differences
should be.
What DOES fix this (i.e. getting always the same XML document) is
sorting the styles (which are read from a dictionary) before
outputting them.
