Naming of templates

Up to now, people on this wiki (at least) have followed the following rules:


 * the roman numeral is used for defining the uppermost piece of the connecting player involved at the beginning.
 * the arabic numeral is used in order to specify the number of pieces of the connecting player involved at the beginning.
 * a letter is used to distinguish between the templates having the same roman and arabic numeral.

Example edge template III-1-a.
