e60e3de474 Added a new minimization package with an implementation of the Brent algorithm 
contributed by Gilles Sadowski.
The implementation needs some testing as it seems to never use the parabola fitting
and only relying on golden section. This may be due to the refactoring I did on
the original patch.

beae2e9891 COMMONSSITE-30 - fix the checkstyle configuration to work for multi-module and review/update <reporting> plugin version numbers for the poms being changed. 
- pom's need to use ${basedir} for configuration files as the multi-module profile is run from commons-parent, so if not specified it can't find those files
 - the checkstyle configuration file needs to use ${checkstyle.header.file} for the headerFile property and  <headerFile> element added to the plugin config in the pom.xml
 - fix m1 checkstyle config to reflect the above where appropriate (specify header file property)
