// The FIELD_DESCRIPTOR data structure is used to describe the field in a structure sufficiently
// for displaying information during debugging. The three pieces of information that are required
// are 1) the name of the field, 2) the offset in the corresponding structure and 3) a type descriptor.
// The type descriptor covers most primitive types.
//
// The task of generating these descriptors by augmenting the front end, but that will have to
// wait till we play around with these extensions and modify the data structures to meet most
// of the requirements.
//
// There are some types that can benefit from some auxillary information in the descriptors. A
// case in point is the "enum" defeinition. Merely printing out a numerical value for an enum
// type will invariably force the person using these extensions to refer to the corresponding
// include file. In order to avoid this we will accept an additional array for enum types that
// contains a textual description of the numerical value.
//
// There are certain conventions that have been adopted to ease the definition of the macros
// as well as facilitate the automation of the generation of these descriptors.
// These are as follows ....
//
// 1) All ENUM_VALUE_DESCRIPTOR definitions are named EnumValueDescrsOf_ENUMTYPENAME, where
// ENUMTYPENAME defines the corresponding enumerated type.
//
