	 uint16_t Packet::txObj(const T &val, const uint16_t &index=0, const uint16_t &len=sizeof(T))
	 Description:
	 ------------
	  * Stuffs "len" number of bytes of an arbitrary object (byte, int,
	  float, double, struct, etc...) into the transmit buffer (txBuff)
	  starting at the index as specified by the argument "index"

	 Inputs:
	 -------
	  * const T &val - Pointer to the object to be copied to the
	  transmit buffer (txBuff)
	  * const uint16_t &index - Starting index of the object within the
	  transmit buffer (txBuff)
	  * const uint16_t &len - Number of bytes of the object "val" to transmit

	 Return:
	 -------
	  * uint16_t maxIndex - uint16_t maxIndex - Index of the transmit buffer (txBuff) that directly follows the bytes processed
	  by the calling of this member function
