Change Tests so that they are more Input/test type, Input, Expected Output

[mr-eggleton]

Then we can display in a GCSE test table type way.

we also need to define them that way more as we are also looking at multiple languages.
if we aren't looking at classes etc. we should stick with low key tests so most python ones are out (at least directly though pytests instrospection would be great)

currently

assert( calcBoilerStatus(19, 22, 18, "OFF") == "ON",  'Boiler should turn ON when too cold.', "logic");

maybe

gcsetest({
  "func":"calcBoilerStatus",
  "testing":"logic",
  "input_type":"valid",
  "inputs":[19, 22, 18, "OFF"],
  "expected":"ON",
  "message":'Boiler should turn ON when too cold.',
  "task":1
})
