shell script that can be sourced to have produce TAP output for test files

setup

• create tests/setup.sh
• create test files, ex tests/example.test.sh
• run tests, and on success call ok <test name> or fail <test name> (or skip <test-name>)

do need to ensure that none of the tests output TAP related output (ex redirecting stdout)

Find the table / table body, and get the rows: $('tbody').children('tr')

For a specific row (ex 12th), find the cells (tds): .eq(11).children('td')

For all the cells, skip those that have an attribute: not('td[rowspan=8]')

Skip over some fixed columns (ex start at column 2): slice(1, 31)

For example on http://www.tshwane.gov.za/sites/Departments/Public-works-and-infrastructure/Pages/Load-Shedding.aspx, to get
