RFR: 8192821 : Make LogCompilation into a maven project

[Eric Caspole]

Hi everyone, please review this change to build the LogCompilation tool 
with Maven rather than a Makefile, so it can easily be imported and used 
with IDEs. This will allow in future for test cases etc and help prevent 
bit rot in this useful tool.
Thanks,
Eric
