Create new project GraphUtils

[sylvainhalle]

• Create a new folder under the Source folder, with the same structure as the Functions project (similar build and config XML files, with the export JAR name being petitpoucet-graphutils.jar:

Source/
+ GraphUtils/
   + src/
   + srctest/
   + build.xml
   + config.xml

• Add GraphUtils to the Source/build.xml file. It should have added entries in the file similar to those handling the Functions project (with folder names modified).
• Add the dependency to the stev-booleans.jar in config.xml; add an entry to this JAR with the <bundle> parameter set to true. Reference to adding dependencies in build.xml: https://github.com/sylvainhalle/AntRun#declaring-dependencies----------------------------------------------deps
