Bit vectors.
This class implements bit vectors with run-time sizes and a rich set of operations that can be restricted to a contiguous subset of bits. The primary goal of this class is not to provide the utmost performance, but rather a rich, easy-to-use interface. For example,
In general, each method has a number of overloaded varieties: if a BitRange is not specified it generally means the entire bit vector; if a second bit vector is not specified for binary operations it generally means use this vector for both operands. Non-const operations modify this vector in place, and most of them also return a reference so that they can be easily chained:
When performing an operation that has two operands, the operands are generally permitted to both refer to the same vector, and the range arguments are permitted to overlap in that vector. When this occurs, the semantics are as if a temporary copy was made, then the operation was performed on the temporary copy, then the result was written back to the destination.
BitVector objects manage their own data, but if one needs to operate on an array that is already allocated then the function templates in the BitVectorSupport name space can be used.

Create a bit vector by reading a string.
Reads a bit vector from the string and returns the result. The input string has an optional suffix ("h" for hexadecimal) or optioanl prefix ("0x" for hexadecimal, "0b" or binary, or "0" for octal). It does not have both; if a suffix is present then the parser does not search for a prefix. Lack of both prefix and suffix implies decimal format. Any recognized suffix or prefix is stripped from the value, and the number of valid digits is counted and used to calculate the width of the resulting bit vector. For instance, if three octal digits are found (not counting the "0" prefix) then the resulting bit vector will have nine bits – three per digit. The string is then passed to fromBinary, fromOctal, fromDecimal, or fromHex for parsing.

Change vector size.
Changes the size of a vector, measured in bits, by either adding or removing bits from the most-significant side of this vector. If new bits are added they are each given the value newBits. Increasing the size of a vector may cause it to reallocate and copy its internal data structures.

Clears bits by assigning false to each bit in the specified range. The convention is that "clear" means to assign false to a bit and should not be confused with the STL usage of the word, namely to erase all values from a container. To erase all bits from a vector, use resize(0).

Shift bits left.
Shifts the bits in the specified range of this vector left (to more significant positions) by nShift bits. Bits shifted off the left of the range are discarded; new bits shifted into the right of the range are introduced with the value newBits. The range must be valid for this vector. If nShift is zero or the range is empty then no operation is performed. Specifying an nShift value equal to or greater than the size of the range has the same effect as filling the range with newBits (see also, set and clear, which are probably more efficient).

Assigns the specified value to this vector. If this vector contains fewer than 64 bits then only the low order bits of value are used; if this vector contains more than 64 bits then the high-order bits are cleared. The size of this vector is not changed by this operation.

Obtains bits from a decimal representation.
Assigns the specified value, represented in decimal, to the specified range of this vector. The input string must contain only valid decimal digits '0' through '9' or the underscore character (to make long strings more readable), or else an std::runtime_error is thrown. The range must be valid for this vector. If the number of supplied digits is larger than what is required to initialize the specified range then the extra data is discarded. On the other hand, if the length of the string is insufficient to initialize the entire range then the high order bits of the range are cleared.

Obtain bits from a hexadecimal representation.
Assigns the specified value, represented in hexadecimal, to the specified range of this vector. The input string must contain only valid hexadecimal digits '0' through '9', 'a' through 'f', and 'A' through 'F', or the underscore character (to make long strings more readable), or else an std::runtime_error is thrown. The range must be valid for this vector. If the number of supplied digits is larger than what is required to initialize the specified range then the extra data is discarded. On the other hand, if the length of the string is insufficient to initialize the entire range then the high order bits of the range are cleared.

Obtain bits from an octal representation.
Assigns the specified value, represented in octal, to the specified range of this vector. The input string must contain only valid octal digits '0' through '7' or the underscore character (to make long strings more readable), or else an std::runtime_error is thrown. The range must be valid for this vector. If the number of supplied digits is larger than what is required to initialize the specified range then the extra data is discarded.

Obtain bits from a binary representation.
Assigns the specified value, represented in binary, to the specified range of this vector. The input string must contain only valid binary digits '0' and '1' or the underscore character (to make long strings more readable), or else an std::runtime_error is thrown. The range must be valid for this vector. If the number of supplied digits is larger than what is required to initialize the specified range then the extra data is discarded. On the other hand, if the length of the string is insufficient to initialize the entire range then the high order bits of the range are cleared.

Obtain bits from a byte vector.
Reads bits from the little-endian byte vector and copies them into the specified range of this bit vector. If no range is specified, then this entire bit vector is initialized. The byte vector must be long enough to initialize the specified range or the whole bit vector.
