Posibility for custom Processor

[jonkerw85]

I would like to have the ability to configure a custom Processor. This because I need to trim the response I get. I get often results with allot of added whitespaces. I have solved this by changing the processSelect function in the DB2Processor class. I would prefer to make this configurable.

I'am wondering if you are willing to add or accept a pull request from me to add this feature.
