implementation report generation

Run the tests

1. Install web platform tests per instructions
2. Safari ./wpt run --log-wptreport "safari.json" --channel=preview safari payment-request/
3. Chrome ./wpt run --log-wptreport "chrome.json" --binary=/Applications/Google\ Chrome\ Canary.app/Contents/MacOS/Google\ Chrome\ Canary chrome payment-request
4. Remove any "tentative" results
5. Move the results to test-results folder (see below!).

Generate the report

Prerequisites

1. The report is generated using wptreport, so, install:

npm install -g wptreport

2. Git clone the following repository:

git clone git@github.com:w3c/test-results.git

Generating the report

1. In the "test-results" repo, navigate to the "payment-request" directory and run wptreport without any arguments. It does not take long to run. It will update "all.html" (and typically other files in the directory).
2. Commit changed files; do a pull request.
