Example usage:
--------------

// Create database object.
$db = new MySQL('myHost', 'myUser', 'myPassword', 'myDatabase');

// Fetch a single value.
$rowCount = $db->fetchOne('
	SELECT COUNT(*)
	FROM `some_table`;
');
printf('Row count: %s', $rowCount);

// Fetch a single row using a single placeholder.
$rawSql = 'SELECT firstname, lastname, age	FROM `persons` WHERE id = ?;'
$id = 123;
$db->bindParam(1, $id);
$sql = $db->prepare($rawSql);

$row = $db->fetchRow($sql);
print_r($row);

// Fetch multiple rows using multiple placeholders.
$firstname = 'Joe';
$minimumAge = 30;
$rawSql = 'SELECT firstname, lastname, age FROM `persons` WHERE firstname = ? AND age > ?;'
$db->bindParam(1, $firstname);
$db->bindParam(2, $minimumAge);
$sql = $db->prepare($rawSql);
$rows = $db->fetchAll($sql);
print_r($rows);

// Insert a row using placeholders with auto-escaping.
$rawSql = 'INSERT INTO `persons` (firstname, lastname, age) VALUES (?, ?, ?);'
$db->bindParam(1, $firstname);
$db->bindParam(2, $lastname);
$db->bindParam(3, $age);
$sql = $db->prepare($rawSql);
$db->query($sql);

// Insert a row using the SQL-free method with an associative array.
$db->insert('persons', array(
	'firstname' => $firstname,
	'lastname' => $lastname,
	'age' => $age
));

// Update a row using associative array
$db->update('persons', array('age' => 123), array('id' => 1));

// Delete a row.
$db->delete('persons', array('age' => 18));
