Bills of exceptions, exceptions pendente lite, assignments of error abolished; contents of motions for new trial and for j.n.o.v

(a) Bills of exceptions, exceptions pendente lite, assignments of error, and all rules relating thereto are abolished. (b) Motions for new trial and for judgment notwithstanding the verdict need not set out portions of the record or transcript of evidence and it shall not be necessary that the grounds thereof be complete in themselves or be approved by the court; provided, however, that the motions must be sufficiently definite to inform the opposite party of the contention of the movant.
