Print the Chevron repeat sample

Start with: No file needed: the built-in sample Chevron repeat (raport practice). A saved copy to try with Open... is in examples/frigella/chevron-repeat.frigella.json.

1. Open your local Frigella page.
2. In Load a sample chart..., choose Chevron repeat (raport practice).
3. Click Export PDF..., then click Export PDF (our test used the default settings).
4. Click Save as... and save the chart file.

Expected result: The status reads “Loaded the "Chevron repeat" sample.” and the chart is 20 sts x 12 rows. Your browser downloads chevron-repeat.pdf. Page 1 is the chart with row and stitch numbers and page 2 is the legend (20 stitches x 12 rows, 2 colours). The saved chevron-repeat.frigella.json opens again with Open....
