<p>
Boost.Accumulators is both a library for incremental statistical computation
as well as an extensible framework for incremental calculation in general.
The library deals primarily with the concept of an <span class="emphasis"><em>accumulator</em></span>,
which is a primitive computational entity that accepts data one sample at a
time and maintains some internal state. These accumulators may offload some
of their computations on other accumulators, on which they depend. Accumulators
are grouped within an <span class="emphasis"><em>accumulator set</em></span>. Boost.Accumulators
resolves the inter-dependencies between accumulators in a set and ensures that
accumulators are processed in the proper order.
