/**
 * Setget
 *
 * This class has been designed to test set/get operations
 * for a specific Query Writer / Adapter. Since RedBeanPHP
 * creates columns based on values it's essential that you
 * get back the 'same' value as you put in - or - if that's
 * not the case, that there are at least very clear rules
 * about what to expect. Examples of possible issues tested in
 * this class include:
 *
 * - Test whether booleans are returned correctly (they will become integers)
 * - Test whether large numbers are preserved
 * - Test whether floating point numbers are preserved
 * - Test whether date/time values are preserved
 * and so on...
 *
 * @file    RedUNIT/Postgres/Setget.php
 * @desc    Tests whether values are correctly stored.
