Functions
input()
Declares a setting the reader can change from the chart, picking its kind from the type of the default value you hand it. Six forms exist. Give it a bool and you get a bool back; give it a colour, a float, an int or a string and the same holds. The sixth takes a series and returns a `series float`, which is how you offer a choice of chart data without naming `input.source`. There are no bounds and no step here — for those, use `input.int` or `input.float`.
