[code-reflection] Integrated: Added mkpoms script - updated bldr/XMLNode

[Gary Frost]

Added the script I have been using to create pom files. 

Also the autogenerated pom.xml files themselves.  We may remove these in future once we prove the above script is good enough


. ./env.bash
java bldr/mkpoms 
bash maven-build.bash
