Support brackets

If I attempt to parse following statement:
(SELECT 1)
With this code:

Statement stmt = CCJSqlParserUtil.parse("(SELECT 1)");

I get following error:

Encountered " "(" "( "" at line 1, column 1.
Was expecting one of:
    "WITH" ...
    "SELECT" ...
    "SELECT" ...

However, the mentioned statement executes correctly on:

• PostgreSQL
• MySQL
• MS SQL SERVER
• Oracle (with: (select 1 from dual))

Use case: Sometimes I want to parse just a portion of a long statement. And if I am not careful enough, parentheses can leak into JSqlParser.
