/**
 * When sent from client to server, form input fields are calculated a new identifier, made by appending the
 * dollar character, followed by the player identifier if defined, followed by another dollar sign, to the
 * initial field name. So, with a field called “name” and player identifier of 3, the field identifier will
 * be “name$3$”, and for a global field called “count” (player identifier is -Infinity), the final field
 * identifier will be “count$$”.
 *
 * This class manages the conversions between the two ways of identifing the fields.
