do over — text permutations

- Want to quickly and easily change the values and template text and see the results in realtime? do over can do that.
- Want to use a different placeholder in the template? do over can do that.
- Want to see how the merged results will look using different joins? do over can do that.
- Want to be successful in life? do over, unfortunately, cannot do that.

Provide a list of values (apple banana coconut … zucchini, for example) along with a template to use (such as ?i. ?), and do over generates merged output:

1. apple
2. banana
3. coconut
…
26. zucchini

do over can do multi-step substitutions as well.
