Add a bunch of test cases

[pokey]

Extracted from #59

• let's use this one to capture Add type transformation #32 (comment) as a test case
• extracting name from exported classes and functions in Typescript
• extracting name from decorated classes and functions in Python
• Delimiters get removed from source of "move" and "cut"
• "that" gets set properly
• Behaviour of "wrap" wrt current selection:
  • Target selected
  • Cursor at beginning of target
  • Cursor at end of target
  • Cursor bigger than target tot left / right / both
  • Multiple cursors? (Eg one cursor at end and one at beginning, etc)
• space delimited sequence support when combined with punctuation, eg for "This is, a test!":
  • "chuck sit"
  • "move sit after each"
  • "move air after each"
  • "move each before air"
  • "bring air before bang"
• Make sure leading delimiter with "chuck type" gets deleted
• Test Fix bug with two adjacent tokens #12 and various overlapping ranges
• "take token" / "take first word" when cursor is at beginning, middle and end of token
• select a token, then wrap it and make sure selection in right place
• Multi-target inference rules, eg "swap funk air with bat", "swap air with funk bat", etc
• Make sure basic things work in unsupported languages
• "move sit to before file"
• "chuck last char air"
• Excluding positions in ranges. take air until bat take air tween bat
• multiple sequential spaces for space delimiter removal
• single-line blocks for line removal
• last line / first line in doc for line removal / space removal
• removing every word in line for space removal
• final / first token in line for space removal
• "Every key" / "every value" / "every arg" in Python
