SYSPHS12 — Naming errors and typos in the Modelica code corresponding to Figure 25

In the exported Modelica code on p.38 the model should be SpringMassSys (not Spring) for consistency with the text:

The block SpringMassSys has a SysML constraint property smsc typed by SMSConstraint.

This then also matches the name of the Parametric diagram SpringMassSys.

The Modelica code portion on p.39 has the incorrect keyword 'equations' not 'equation'.

The following equation incorrectly uses the variable 'm' instead of 'mass':

der(velocity)=(u-springcst*position)/m;

Should be:

der(velocity)=(u-springcst*position)/mass;
