Refactor: rename matcher.js to create-matcher.js

[mroderick]

This PR renames the poorly named function match in matcher.js to createMatcher in create-matcher.js, which better describes what the function does.

It is already exported as samsam.createMatcher, so no new release is required.

Background

I am trying to cover this library in JSDoc comments, understanding what this function does has always been a struggle.

This has been unlocked by #84, which fixed is-element.test.js to not fail when load order changes.

This PR paves the way for #82

Solution

Rename the file(s) and the name of the function that is exported (not the name it is exported under though).

How to verify - mandatory

1. Observe that tests still pass

• npm run lint passes
