Added module folder and POM
Added initial draft of DataContextFactoryBean with support for JDBC, CSV
and Excel
Added testcases for CSV datacontext factory
Added test case for Excel data contexts.
Made the DataContextFactoryBean extensible by making it possible to
specify delegate classes as the "type" parameter. This also avoids
runtime dependencies on unwanted MetaModel modules, since the factory
class no longer directly imports foreign module code.
Minor changes to fit in with rat and enforcer rules.
Improvement to javadoc
Merge branch 'spring-module' into master
