[Documentation] Update model.model.IsolabilityAnalysisARR

[blaab2]

In the current version of the toolbox (01e3939) the method is named
model.IsolabilityAnalysisArrs
therefore the documentation on page 15 should be updated from
model.IsolabilityAnalysisARR(msos([1,3]));
to
model.IsolabilityAnalysisArrs(msos([1:3]));

Furthermore on page 15
FSM = model.FSM(Msos([1,3]));
should be replaced by
FSM = model.FSM(msos([1,3]));
to ensure consistency.
