class TBits: public TObject

 Set bit number 'bitnumber' to be value

 Return the current value of the bit

 Flips the bit

----- bit manipulation
----- (note the difference with TObject's bit manipulations)

----- Accessors and operator

----- Optimized setters
 Each of these will replace the contents of the receiver with the bitvector
 in the parameter array.  The number of bits is changed to nbits.  If nbits
 is smaller than fNbits, the receiver will NOT be compacted.

----- Optimized getters
 Each of these will replace the contents of the parameter array with the
 bits in the receiver.  The parameter array must be large enough to hold
 all of the bits in the receiver.
 Note on semantics: any bits in the parameter array that go beyond the
 number of the bits in the receiver will have an unspecified value.  For
 example, if you call Get(Int*) with an array of one integer and the TBits
 object has less than 32 bits, then the remaining bits in the integer will
 have an unspecified value.
