better data-security with given variable-types

[Gummibeer]

it would be nice if the SecureData-function could be extended by variable-taypes like in the Wordpress database-class (https://codex.wordpress.org/Class_Reference/wpdb#INSERT_rows).
This can increase the database-security much more and ensure that no values enter the db that shouldn't.
i think that types like string, integer, float, boolean (true/false || 1/0) and datetime date timestamp would be nice.

with the changes it should be, for example:

$newUser = array('username' => 'Thrackhamator');
$types = array('str');
$oMySQL->insert('admin', $newUser, '', $types);

You can think about changing the position of the types-arguments. For example public function insert($table, $vars, $datatypes, $exclude = ''){

@a1phanumeric It's important to update your readme now! All public funtions are lowercase #35 and the most got a new agrument, wich is required cause without it will write an empty string into the database.
