Create a feature which will allow easy navigation to / or generation of related files (e.g. from a unit test, the source, from the source the unit test, from the unit test the benchmark, etc. etc. etc.)

Below each target represents an aspect of the source code, for example

• Source
• Unit test
• Benchmark

The kernel is the part of the file name (or class name) which remains constant.

When the teleporter is invoked:

• We replace <kernel> with (.*?) and run a regex on the current file name
  for each of the targets and find a match.
• We offer the user a choice of destinations from the remaining targets.
• When selected the kernel is replaced in the selected target
• The file is opened, if it does not exist it is created (using the existing
  create functionality).

teleport:
    targets:
        source: 
            pattern: "src/<kernel>.php$"
            create: default
        phpunit: 
            pattern: "tests/Unit/<kernel>Test.php$"
            create: phpunit_test
        benchmark: 
            pattern: "benchmark/<kernel>Bench.php$"
            create: benchmark
