Lowered.java:58-62: Introduce text.Mapped that takes a...

[0pdd]

The puzzle 1287-1c7c8289 from #1287 has to be resolved:

cactoos/src/main/java/org/cactoos/text/Lowered.java

Lines 58 to 62 in 47aff6e

	* @todo #1287:30min Introduce `text.Mapped` that takes a `Text` and
	* a `Func` from `String` to `String`. Add some tests (included for
	* `equals`). Once it is done, replace the code below by the use of
	* `text.Mapped`. Do the same for all the one-liner mapping of the
	* `text` package (e.g., `Upper`, `Trimmed`).

The puzzle was created by Victor Noël on 13-Sep-20.

Estimate: 30 minutes, role: DEV.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.

The puzzle 1287-1c7c8289 has disappeared from the source code, that's why I closed this issue.
