NEW:
new SingleBreakOrContinue - This check restricts the number of break and continue statements inside cycle body (only one is allowed).
new NumericLiteralNeedsUnderscore - This check verifies that large numeric literals are spaced by underscores.
Bugs:
Rename checks to follow Checkstyle convention for check names. Checks AvoidDefaultSerializableInInnerClasses, ForbidCCommentsInMethods, ReturnBooleanFromTernary, ReturnNullInsteadOfBoolean renamed to have "Check" as suffix in name.
