The type parameters of Db\Driver::prepare() and the parameters of Db\Statement::run() can now be arrays, which will be iterated over recursively to bind scalar values to the SQL statement.
This simplifies the construction of arbitrary UPDATE statements (the WHERE clause no longer needs to be taken into account) and should make it clearer what is happening in these cases.
It should also simplify the creation of IN() clauses down the road if they become necessary.
- Introduced abstract Statement class to hold common methods
- Common methods currently consist of a date formatter and type caster
- Moved binding tests to a trait for reuse with future drivers
