* Name: BITS
* Description: Holds information for processing the input data buffer
* as a "stream". The data is in packed format.
* Fields:
* pBuffer - pointer to the beginning of the buffer. If the data type of
* this changes, make sure to update the constants in ibstream.h
* usedBits - number of bits read thus far from the buffer. Bit 0 is
* the LSB of pBuffer[0].
