Hi --

I am working on a project that needs to write data to a file in a specific
pattern. I have two arguments: a number from 0-15, and a long. I need to
write the first number in 4 bits, and then the last 20 bits of the long
(the first bits should be zero, but not necessarily). I also need to be
able to read these 3-bit sets. InputStream and OutputStream only read
bytes, and I cannot convert it to a BitSet. Memory space is important, so
simply writing the full long is not an option.
