    Returns a term name that is unique within this instance of a CodeGenerator.

    (Since we aren't in a macro context we do not seem to have access to the built in freshName function.)

    c1

    name of the variable of expression 1's output

    c2

    name of the variable of expression 2's output

25. def genEqual(dataType: DataType, c1: String, c2: String): String

    Holding expressions' mutable states like MonotonicallyIncreasingID.count as a 3-tuple: java type, variable name, code to init it. As an example, ("int", "count", "count = 0;") will produce code:

    private int count;

    as a member variable, and add

    count = 0;

    to the constructor.

    They will be kept as member variables in generated classes like SpecificProjection.
