Complete assign expression (ex. variable1=value1) mapped correctly to the assign variable and value

On a assign it would be good when we put variable=value on the variable side, the platform puts the value automatically on value side.

Example:

Inserting this: 

EntityTestValid.IsValidAttribute1=False

The platform automatically transforms in the assign to variable EntityTestValid.IsValidAttribute1 and Value False.

This would save time, specifically when pasting code from Lessons exercises and would allow us set an assign without having to change the input focus.
