+ \brief
+ This class provides several helper functions to generate properly
+ formatted GAP Advertising and Scan Response data payloads
+
+ \note
+ See Bluetooth Specification 4.0 (Vol. 3), Part C, Section 11 and 18
+ for further information on Advertising and Scan Response data.
+
+ \par Advertising and Scan Response Payloads
+ Advertising data and Scan Response data are organized around a set of
+ data types called 'AD types' in Bluetooth 4.0 (see the Bluetooth Core
+ Specification v4.0, Vol. 3, Part C, Sections 11 and 18).
+
+ \par
+ Each AD type has it's own standardized 'assigned number', as defined
+ by the Bluetooth SIG:
+ https://www.bluetooth.org/en-us/specification/assigned-numbers/generic-access-profile
+
+ \par
+ For convenience sake, all appropriate AD types have been encapsulated
+ into GapAdvertisingData::DataType.
+
+ \par
+ Before the AD Types and their payload (if any) can be inserted into
+ the Advertising or Scan Response frames, they need to be formatted as
+ follows:
+
+ \li \c Record length (1 byte)
+ \li \c AD Type (1 byte)
+ \li \c AD payload (optional, only present if record length > 1)
+
+ \par
+ This class takes care of properly formatting the payload, performs
+ some basic checks on the payload length, and tries to avoid common
+ errors like adding an exclusive AD field twice in the Advertising
+ or Scan Response payload.
+
+ \par EXAMPLE
+
+ \code
+
+ // ToDo
+
+ \endcode
