Dynamic expression evaluation version 2.

This primitive has four fixed number of column inputs, and allows up to four constants to be specified via configuration. The operation between the column values and constants can be defined dynamically through the configuration at run-time. The same configuration is used for all rows until the end of input.

The constant numbers are assumed to be no more than 32-bits.
