Added examples folder containing a plain text changelog template (file.mustache) and a HTML changelog template (module.mustache).
Added target folder, nbactions and the like to .gitignore.
changelog-file-name parameter now accepts a CSV list of filenames for output. The number of output files must match the number of supplied template files.
Updated test case class to reflect directory and parameter changes.
