cpp, elixir and x86-64-assembly all have a pretty similar intro doc for this exercise. This PR tidies up some of the differences between them (merging in improvements) and brings swift onboard with them.

I often mix up the terms "argument" and "parameter" myself, but should this new text use "arguments"?
Because a function has parameters but takes arguments.

[IsaacG]

should this new text use "arguments"?

Hrm. Probably. I could make that change across the various tracks.

[IsaacG]

What about lines 17 and 30?

Implement a function called daily_rate to calculate the daily rate given an hourly rate as a parameter.

It should accept two parameters: the original price and the discount rate in percent.

Should those be changed, too?

[siebenschlaefer]

Good catch. IMHO yes.

There are probably more of these on the track. I remember I had a discussion about this with Siebenschläfer, so we might have correct some of those.
