This test uses the CParser to parse all datatypes defined by zeroarray.h.
The parse process entails building up the composite types using the various 
"Impl" datatypes followed by their being resolved into the associated datatype
manager where DB datatypes will be established.
<br>
When fetching datatypes from the datatype manager they will naturally be 
returned as DB datatypes when applicable (see {@link #getStructure(String)} and 
{@link #getUnion(String)}).  If the test class name contains "Impl" a deep copy 
will be performed on datatypes to return as an non-DB Impl datatype.
