classSqlIdentifierComponent
final class SqlIdentifierComponentReads one part of a name out of the tokens a statement was written as.
A name may be written bare or in whatever the dialect quotes identifiers with, and a quoted one carries escapes that are not part of the name. Both spellings answer the same name, and anything that is not a name at all answers nothing.
