> In some situations we would like to store the whole text, but the whole text won't always
fit in memory so we can't create a String.  Likewise for storing binary, it would sometimes
be better if we didn't have to read into a byte[] up-front (even when it doesn't use much
memory, it increases the number of copies made and adds burden to GC.)
> FieldsWriter currently writes the length at the start of the chunks though, so I don't
know whether it would be possible to seek back and write the length after writing the data.
> It would also be useful to use this in conjunction with compression, both for Reader
and InputStream types.  And when retrieving the field, it should be possible to create a Reader
without reading the entire String into memory up-front.
