Determine where the input $source argument is a callback function, a set
of arrays, or neither. If $source is a callback function, run it through
the functionToPoints() method with the input $args, and set $points to
output array. If $source is a set of arrays, simply set $points to
$source. If $source is neither, throw an Exception.

| $source | The source of our approximation. Should be either a callback function or a set of arrays. | |
| $args | array | The arguments of our callback function: derivative, start, end, and n. Example: [$derivative, 0, 8, 5]. If $source is a set of arrays, $args will default to []. |
