Clean Up Testing Class Instantiations

[pbauman]

Before it occurred to me to use a macro, there's at least 3 different testing classes to get registered with CppUnit (float, double, long double). Of course, this make it easy to add a test to one and forget the others. In #240, it occurred to me we can use a macro along these lines:

#define DEFINE_NASA7XMLPARSING_SCALAR_TEST(Classname,BaseClass,Scalar)  \
  class Classname : public BaseClass                            \
  {                                                                     \
  public:                                                               \
    CPPUNIT_TEST_SUITE( Classname );                                    \
    CPPUNIT_TEST(test_supplied_species);                                \
    CPPUNIT_TEST(test_parsed_species_list);                             \
    CPPUNIT_TEST(test_gri30_xml);                                       \
    CPPUNIT_TEST_SUITE_END();                                           \
  }

DEFINE_NASA7XMLPARSING_SCALAR_TEST(NASA7XMLParsingTestFloat,NASA7XMLParsingTest,float);
DEFINE_NASA7XMLPARSING_SCALAR_TEST(NASA7XMLParsingTestDouble,NASA7XMLParsingTest,double);
DEFINE_NASA7XMLPARSING_SCALAR_TEST(NASA7XMLParsingTestLongDouble,NASA7XMLParsingTest,long double);


CPPUNIT_TEST_SUITE_REGISTRATION( NASA7XMLParsingTestFloat );
CPPUNIT_TEST_SUITE_REGISTRATION( NASA7XMLParsingTestDouble );
CPPUNIT_TEST_SUITE_REGISTRATION( NASA7XMLParsingTestLongDouble );

where the base testing class is templated on the Scalar type.

So let's go back and clean up all the other tests that aren't doing this.

Hmm, the mark down is munging the public BaseClass<Scalar>
