findBytes -- Search for Bytes in Byte Array

The findBytes method returns the index of the first matching byte sequence in the binary bytes contained in a CkByteData object. A return value of 0 indicates that the data begins with the bytes. A return value of -1 indicates that the byte sequence was not found.
