This cursor will execute statements and handle the result. It will not automatically
fetch all rows.
MySQLCursor should be inherited whenever other functionallity is required.
An example would to change the fetch* member functions to return dictionaries instead
of lists of values.
Implements the Python Database API Specification v2.0 (PEP-249).

The arguments will be set during this session, meaning
they will be called like ___arg where
is an enumeration (+1) of the arguments.
Coding Example:
1) Defining the Stored Routine in MySQL:
CREATE PROCEDURE multiply(IN pFac1 INT, IN pFac2 INT, OUT pProd INT)
BEGIN
SET pProd := pFac1 * pFac2;
END
2) Executing in Python:
args = (5, 5, 0) # 0 is to hold pprod
await cursor.callproc('multiply', args)
print(await cursor.fetchone())
For OUT and INOUT parameters the user should provide the
type of the parameter as well. The argument should be a
tuple with first item as the value of the parameter to pass
and second argument the type of the argument.
In the above example, one can call callproc method like:
args = (5, 5, (0, 'INT'))
await cursor.callproc('multiply', args)
The type of the argument given in the tuple will be used by
the MySQL CAST function to convert the values in the corresponding
MySQL type (See CAST in MySQL Reference for more information)
Does not return a value, but a result set will be
available when the CALL-statement execute successfully.
Raises exceptions when something is wrong.

This method will prepare the given operation and execute it using
the optionally given parameters.
If the cursor instance already had a prepared statement, it is
first closed.

xZ S )MySQLCursorPreparedDicta
This class is a blend of features from MySQLCursorDict and MySQLCursorPrepared
Multiple inheritance in python is allowed but care must be taken
when assuming methods resolution. In the case of multiple
inheritance, a given attribute is first searched in the current
class if it's not found then it's searched in the parent classes.
The parent classes are searched in a left-right fashion and each
class is searched once.
Based on python's attribute resolution, in this case, attributes
are searched as follows:
1. MySQLCursorPreparedDict (current class)
2. MySQLCursorDict (left parent class)
3. MySQLCursorPrepared (right parent class)
4. MySQLCursor (base class)

as a list of dictionaries where column names are used as keys.
