2019-12-20 Running M4 methods with OPTIMIZEKEL == 1 results in computation error

[jhhughes256]

When running an M4 method with OPTIMIZEKEL == 1 a computation error occurs. This is long-standing behaviour for the computation engine. This raises the following questions.

• Is OPTIMIZEKEL supported for M4?
• If not, do users have the ability to active OPTIMIZEKEL in the application when running the M4 method?
• If so, should users be provided with a more informative error that OPTIMIZEKEL is not supported for M4?

Current error below.
