+ * data type declarations (section B.1.3.3 - Derived data types) we use a top->bottom approach.
+ * This is intentional, and not a bug! Explanation follows...
+ * Here we are essentially determining the base type of each defined data type. In many cases (especially structs,
+ * enumerations, arrays, etc...), the datatype is its own base type. However, the derived datatype is stored in
+ * multiple symbol_c classes (e.g. an enumeration uses enumerated_type_declaration_c, enumerated_spec_init_c,
+ * enumerated_value_list_c, enumerated_value_c, ...). Several of these could be chosen to work as the canonical base datatype
+ * symbol. Which symbol is used is really up to the search_base_type_c, and not this fill_candidate_datatypes_c.
+ * Here we must right the code to handle whatever the search_base_type_c chooses to use as the canonical symbol to represent
+ * the base datatype.
+ * Since the base datatype may be (and sometimes/often/always(?) actually is) the top level symbol_c (an enumerated_type_declaration_c
+ * in the case of the enumerations), it only makes sense to ask search_base_type_c for a basetype when we pass it the
+ * symbol in the highest level of the type declaration (the enumerated_type_declaration_c in the case of the enumerations).
+ * For this reason, we determine the basetype at the top level, and send that info down to the bottom level of the data type
+ * declaration. In summary, a top->down algorithm!
