 /**
 * @brief These adapters provides an interface to use the SerializeIF functions
 * 		  with arbitrary template objects to facilitate and simplify the
 * 		  serialization of classes with different multiple different data types
 * 		  into buffers and vice-versa.
 * @details
 *
 * A report class is converted into a TM buffer. The report class implements a
 * serialize functions and calls the AutoSerializeAdapter::serialize function
 * repeatedly on all object data fields. The getSerializedSize function is
 * implemented by calling the AutoSerializeAdapter::getSerializedSize function
 * repeatedly on all data fields.
 *
 * The AutoSerializeAdapter functions can also be used as an alternative to
 * memcpy to retrieve data out of a buffer directly into a class variable
 * with data type T while being able to specify endianness. The boolean
 * bigEndian specifies whether an endian swap is performed on the data before
 * serialization or deserialization.
 *
 * There are three ways to retrieve data out of a buffer to be used in the FSFW
 * to use regular aligned (big endian) data. Examples:
 *
 *   1. Use the AutoSerializeAdapter::deSerialize function
 *		The pointer *buffer will be incremented automatically by the typeSize
 *		 of the object, so this function can be called on &buffer repeatedly
 *		without adjusting pointer position. Set bigEndian parameter to true
 *		to perform endian swapping, if necessary
 *		@code
 *   	uint16_t data;
 *   	int32_t dataLen = sizeof(data);
 *   	ReturnValue_t result =
 *   			AutoSerializeAdapter::deSerialize(&data,&buffer,&dataLen,true);
 *   	@endcode
 *
 *   2. Perform a bitshift operation. Watch for for endianness:
 *		@code
 *   	uint16_t data;
 *   	data = buffer[targetByte1] << 8 | buffer[targetByte2];
 *   	data = EndianSwapper::swap(data); //optional, or swap order above
 *   	@endcode
 *
 *   3. memcpy or std::copy can also be used, but watch out if system
 *   	endianness is different from required data endianness.
 *   	Perform endian-swapping if necessary.
 *		@code
 *   	uint16_t data;
 *   	memcpy(&data,buffer + positionOfTargetByte1,sizeof(data));
 *   	data = EndianSwapper::swap(data); //optional
 *   	@endcode
 *
 * When serializing for downlink, the packets are generally serialized assuming
 * big endian data format like seen in TmPacketStored.cpp for example.
