9.3.5 FromHexString

void FromHexString(const std::string &str)
void FromHexString(const char *str)

The FromHexString method converts a hexadecimal string, in either upper, lower or mixed case, into an OEBitVector. The OEBitVector is resized to four times the length of the specified string, each character or hex digit corresponding to four bits. All characters outside the ranges '0'..'9', 'A'..'F' and 'a'..'f' are treated as zero.
