Cryptic error message with ill-defined or missing osp:FixedStepMaster in SSP

[markaren]

This may be nitpicking, but the following error message is a bit "out there" when the user does not properly define the

<ssc:Annotation type="org.open-simulation-platform">
  <osp:SimulationInformation>
     <osp:FixedStepMaster description="FixedStepAlgorithm" stepSize="0.05"/>
  </osp:SimulationInformation>
 </ssc:Annotation>

e.g by misspelling FixedStepMaster

The error:

Error: cse::fixed_step_algorithm::impl::impl: Input requirement not satisfied: baseStepSize.count() > 0

I agree. No errors generated by CSE_INPUT_CHECK() should ever be shown to the user. They are for the programmers' benefit alone.

In fact, I'd say that all std::logic_error-derived exceptions point to program errors, not user errors. (It's kind of analogous to the Error and RuntimeException classes in Java.) In CSE CLI I've made this explicit by prepending such error messages (if they ever occur) with "Internal error:" rather than just "Error:" to make it obvious that the programmer is to blame, not the user.
