/**
 * ({@code @wurblet}) Generate code to select an entity.
 * 
 * usage:

 * @wurblet <tag> PdoSelectUnique
 *     [--private] [--noif] [--append=<sqltext>] [--classvar=<classvariables>]
 *     [--sort] [--lock]
 *     <expression>
 * 

 * arguments:
 * 

 * --private: makes the method private (default is public).
 * --noif: there is no interface (don't generate @Override).
 * --append=<sqltext>: appends an sql-string.
 * --classvar=<classvariables>: reference to classvariables, if pick the statement-IDs from there.
 * --sort: sort according to orderBy()-method.
 * --lock: generates SELECT FOR UPDATE.
 * <expression>: see {@link WurbletArgumentParser}.
 * 
 * For more options, see {@link DbModelWurblet}.
