Reviewed by Tim Nguyen.

Implementing the text representation for the integer counter value
for a defined counter-style.

The text representation is specified at https://www.w3.org/TR/css-counter-styles-3/#counter-styles

A key point of the text representation is the algorithm used, which is
defined by the counter-style system. Each algorithm
is defined at https://www.w3.org/TR/css-counter-styles-3/#counter-style-system
