It would be useful for the performance plugin to be able to recognize several files as results for the same test. This means that we could have a set of results files like:
test1_1.jtl, test1_2.jtl, test1_3.jtl and the plugin should be able to recognize these as results for different runs of the same test.
One way to achieve this would be to allow the user to enter a regexp pattern to be matched against all the result files.
