Missing doxygen groupings

[ischoegl]

Problem description

While Cantera's C++ core provides detailed information on classes and functions, many classes and functions lack @ingroup labels that would generate convenient structures of the doxygen-generated HTML pages, specifically the Modules tab.

For others, @ingroup are defined, but there is no associated @defgroup. Examples are:

• @ingroup electrochem
• @ingroup odeGroup
• @ingroup globalUtilFuncs

Beyond, the generated output may often not be what was intended:

• @defgroup physConstants misses most defined constants (proposed resolution in Update doxygen Chemical Kinetics/Numerics Documentation #1534)
• @defgroup intGroup and @defgroup relatedProps define no methods/classes.
• @defgroup solvesp_methods and @defgroup solvesp_bulkFunc add no useful information.

In either case, the list is likely incomplete.

As an aside, some of the newer Cantera capabilities do not show up in the Modules drop-down (example: AnyValue / AnyMap), and some of the groupings could be better structured.
