/** \brief Value type for a filtration function on a cell complex.
*
* A <EM>filtration</EM> of a cell complex (see FilteredComplex) is
* a function \f$f:\mathbf{K} \rightarrow \mathbb{R}\f$ satisfying \f$f(\tau)\leq
* f(\sigma)\f$ whenever \f$\tau \subseteq \sigma\f$. Ordering the simplices
* by increasing filtration values (breaking ties so as a simplex appears after
* its subsimplices of same filtration value) provides an indexing scheme
* (see IndexingTag).

/** \brief Operator < is a StrictWeakOrdering. */
