/**
 * Abstract query with WHERE conditions generation support. Provides simplified way to generate
 * WHERE tokens using set of where methods. Class support different where conditions, simplified
 * definitions
 * (using arrays) and closures to describe nested conditions:
 *
 * 1) Simple token/nested query or expression
 * $select->where(new SQLFragment('(SELECT count(*) from `table`)'));
 *
 * 2) Simple assessment
 * $select->where('column', $value);
 * $select->where('column', new SQLFragment('CONCAT(columnA, columnB)'));
 *
 * 3) Assessment with specified operator (operator will be converted to uppercase automatically)
 * $select->where('column', '=', $value);
 * $select->where('column', 'IN', [1, 2, 3]);
 * $select->where('column', 'LIKE', $string);
 * $select->where('column', 'IN', new SQLFragment('(SELECT id from `table` limit 1)'));
 *
 * 4) Between and not between statements
 * $select->where('column', 'between', 1, 10);
 * $select->where('column', 'not between', 1, 10);
 * $select->where('column', 'not between', new SQLFragment('MIN(price)'), $maximum);
 *
 * 5) Closure with nested conditions
 * $this->where(function(AbstractWhere $select){
 *      $select->where("name", "Wolfy-J")->orWhere("balance", ">", 100)
 * });
 *
 * 6) Simplified array based condition definition
 * $select->where(["column" => 1]);
 * $select->where(["column" => [
 *      ">" => 1,
 *      "<" => 10
 * ]]);
 *
 * Tokens "@or" and "@and" used to aggregate nested conditions.
 * $select->where([
 *      "@or" => [
 *          ["id" => 1],
 *          ["column" => ["like" => "name"]]
 *      ]
 * ]);
 *
 * $select->where([
 *      "@or" => [
 *          ["id" => 1], ["id" => 2], ["id" => 3], ["id" => 4], ["id" => 5]
 *      ],
 *      "column" => [
 *          "like" => "name"
 *      ],
 *      "x" => [
 *          ">" => 1,
 *          "<" => 10
 *      ]
 * ]);
 *
 * To describe between or not between condition use array with two arguments.
