-- | A streamable, seekable, zoomable cache file format
--   
--   zoom-cache is a fairly simple data file format for storing and
--   summarizing streams of time-series data. The purpose of this format is
--   to make it easy to quickly generate plots; <i>zooming</i> refers to
--   being able to render a window of data, and being able to quickly
--   change the bounds of the window: to move around and to zoom in and
--   out.
--   
--   This library provides a monadic writing and an iteratee reading
--   interface for zoom-cache files.
--   
--   What's neat about this format and library? Glad you asked!
--   
--   <ul>
--   <li>Data can be stored at variable or constant rates. For variable
--   rate data, a timestamp is explicitly written into the file for every
--   value, which is useful for recording events that occur at
--   unpredictable times. Constant rate is useful for regularly sampled
--   data, like most digital audio and video recordings.</li>
--   <li>While writing a file, summary blocks (such as minimum, maximum,
--   mean and RMS values) are written out every n samples. The summary
--   blocks are hierarchical, such that after two have been written, a new
--   one containing a merged summary of those is written. After two of
--   those Level 1 summary blocks have been written, a new Level 2 summary
--   block combining those is written, and so on.</li>
--   <li>You can write your own zoom-cache codecs for custom data types, or
--   to implement custom summary functions. In order to do so you provide a
--   <a>Summary</a> data type, functions for encoding and decoding raw data
--   values and summaries, and a function for merging <a>Summary</a>
--   blocks. For details, see <a>Data.ZoomCache.Codec</a>.</li>
--   <li>Writing of raw data blocks is optional, under control of the
--   application. If you already have the raw data stored in an easily
--   accessible format, your zoom-cache files may just contain the summary
--   data. On the other hand, if your input data is the result of expensive
--   calculations you may want to store it along with the summary data so
--   that plots of any level of detail can be rendered from a single
--   file.</li>
--   </ul>
--   
--   When developing applications that read or write zoom-cache files, it
--   should be sufficient to import only the module <a>Data.ZoomCache</a>.

--   Variable-length coding format:
--   
--   zoom-cache includes a simple variable-length coding scheme for signed
--   integers. When decoding, single bytes are read at a time. If the high
--   bit is set, the next byte is also read. The lower 7 bits of each byte
--   contain data. Decoding continues by reading single bytes until a byte
--   is read with the high bit zero.
--   
--   The first byte of a variable-length coded integer contain a sign bit
--   and the lowest 6 bits of the value. This byte is encoded as:
--   
--   <pre>
--    0 1 2 3 4 5 6 7
--   +-+-+-+-+-+-+-+-+
--   |s| d[0]-d[5] |c|
--   +-+-+-+-+-+-+-+-+
--   </pre>
--   
--   Subsequent bytes encode bits 6-12, 13-19, ... of the value:
--   
--   <pre>
--    0 1 2 3 4 5 6 7
--   +-+-+-+-+-+-+-+-+
--   | d[n]-d[n+6] |c|
--   +-+-+-+-+-+-+-+-+
--   </pre>
--   
--   where <tt>n = 6, 13, 20, ...</tt>
--   
--   <tt>s</tt>: sign, 1 = negative, 0 = non-negative
--   
--   <tt>c</tt>: continue flag, 1 = continue reading next byte, 0 = stop
