/**
 * Initialise fixtures for the league using a round-robin algorithm.
 * Each team plays once per match day. Fixtures are scheduled according to the provided scheduling parameters.
 * Teams will play each other `this.settings.timesTeamsPlayOther` times, with home and away fixtures balanced
 * as per the cycles of the round-robin generation (e.g., first cycle A vs B, second cycle B vs A).
 *
 * @param {object} league - The league instance
 * @param {Date} [startDate] - The start date for the first round of matches. If null, matches will have null dates.
 * @param {Object} [schedulingParams] - Advanced scheduling parameters
 * @param {string} [schedulingParams.schedulingPattern='interval'] - 'interval' or 'dayOfWeek'
 * @param {number} [schedulingParams.intervalNumber=1] - Number of interval units between match days
 * @param {string} [schedulingParams.intervalUnit='weeks'] - 'days' or 'weeks'
 * @param {Array<number>} [schedulingParams.selectedDays] - Array of day numbers (0=Sunday, 1=Monday, etc.) for dayOfWeek pattern
 * @param {number} [schedulingParams.maxMatchesPerDay] - Maximum matches per day (defaults to maxRinksPerSession if not provided)
 * @returns {boolean} - True if fixtures were successfully created, false if there are fewer than 2 teams or if a match fails to be added.
