Problem 22: Names scores

Problem statement

Using names.txt (right click and 'Save Link/Target As...'), a 46K text file containing over five-thousand first names, begin by sorting it into alphabetical order. Then working out the alphabetical value for each name, multiply this value by its alphabetical position in the list to obtain a name score.

For example, when the list is sorted into alphabetical order, COLIN, which is worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list. So, COLIN would obtain a score of 938 × 53 = 49714.

What is the total of all the name scores in the file?

Well, this will be the first time I'll be using rust's i/o interface.

...

This turned out to also be my first use of rust's match feature.

That wasn't so bad. I find I'm doing a lot of these problems so far using the iterator on ranges or lists, then mapping them possibly multiple times using inline |x|-style functions.

Basically, approaching these programs very much like shell pipelines, and not very often with traditional C-like control flows. That's probably okay.
