Detailed Description

Class BitVec defines a bit-vector as an array of BitVecType.

Necessary for space-filling curve. Bit are numbered from O; i.e. The MSB of BitVec[0] is bit 0 and the LSB of BitVec[Dim-1] is bit NBit-1 where NBit=Sizeof(BitVecType)*Dim. Operations on the bit vector include testing/setting and toggleing a set of bits corresponding to a digit and isolating the bits. This class has been modified to have a fix maxlen of the bitvector so that it does not need dynamic allocations.
