Closes exercism#397. This exercise requires that students implement a `hashmap!` macro to simplify creation of hashmap literals. The intent is to gently introduce macros-by-example by having them implement a macro which is both simple but useful. The [maplit crate](https://crates.io/crates/maplit) which inspired this exercise uses the [MIT license](https://opensource.org/licenses/MIT), which as far as I can tell permits this derivative use of its code. Used first edition book link in the readme because second edition's macros chapter is not yet written.

I hope I do not disappoint by saying there is nothing I would change. Maybe one thing about the description, but nothing about the exercise code. Feel free to take the suggestion or not.
In an ideal world, I would attempt to complete this exercise myself before approving it, but that will not be possible.

I feel like this extra line could go, unless it is very important to have two newlines after the title
