Tolong jelaskan mengenai Peranan dari Gray's Inn dalam bahasa melayu

Gray's Inn, along with the other three Inns of Court, remains one of the only bodies legally allowed to call a barrister to the Bar, allowing him to practise as a barrister in England and Wales. Although the Inn was previously a disciplinary and teaching body, these functions are now shared between the four Inns, with the Bar Standards Board (a division of the General Council of the Bar) acting as a disciplinary body and the Inns of Court and Bar Educational Trust providing education. The Inn remains a collegiate self-governing, non-incorporated association of its members, providing within its precincts library, dining, residential and office accommodation (chambers), along with a chapel. To some extent members of the Bar from other Inns may use these facilities.
