Tests the comparison API for using default function comparison model. Each test verifies that
the underlying data model looks correct following a particular API method 
call. There are a few tests that also exercise various features of the data
model directly.
<ul>
<li>The API methods being tested: {@link FunctionComparisonService}</li>
<li>The model being used for verification: {@link AnyToAnyFunctionComparisonModel}</li>
</ul>
