/*
* Standardized way to define a group of registers and corresponding data structures. To define
* a new register set, first define struct containing an enumeration called "Id" containing
* all register IDs and a template struct called "Struct". Specialize the Struct struct for any
* register ID which needs to be accessed in a specialized way. You can then declare the object
* containing all register values using the RegisterSet<BaseType, DefiningStruct> type, where
* BaseType is the underlying type of each register (e.g. u32).
* Of course, you'll usually want to implement the Struct template such that they are of the same
* size as BaseType. However, it's also possible to make it larger, e.g. when you want to describe
* multiple registers with the same structure.
*
* Example:
*
* struct Regs {
* enum Id : u32 {
* Value1 = 0,
* Value2 = 1,
* Value3 = 2,
* NumIds = 3
* };
*
* // declare register definition structures
* template<Id id>
* struct Struct;
* };
*
* // Define register set object
* RegisterSet<u32, CommandIds> registers;
*
* // define register definition structures
* template<>
* struct Regs::Struct<Regs::Value1> {
* union {
* BitField<0, 4, u32> some_field;
* BitField<4, 3, u32> some_other_field;
* };
* };
*
* Usage in external code (within SomeNamespace scope):
*
* For a register which maps to a single index:
* registers.Get<Regs::Value1>().some_field = some_value;
*
* For a register which maps to different indices, e.g. a group of similar registers
* registers.Get<Regs::Value1>(index).some_field = some_value;
*
*
* @tparam BaseType Base type used for storing individual registers, e.g. u32
* @tparam RegDefinition Class defining an enumeration called "Id" and a template<Id id> struct, as described above.
* @note RegDefinition::Id needs to have an enum value called NumIds defining the number of registers to be allocated.
