## Classes
class | fv::GenFunction
| Parent class to all Function classes. More...
class | fv::Function< R(ArgTypes...)>

class | fv::Value< T >
| A templated value. More...
class | fv::ObservedValue< T >
| A value supplied by the dataset, not derived. More...
class | fv::DerivedValue< T >
| A Value derived from some other Values, not directly from the dataset. More...
class | fv::WrapperVector< T >
| A std::vector wrapper around a C-style array. More...
class | fv::Pair< T1, T2 >
| Creates a std::pair type from a two other Value objects. More...
class | fv::Zip< ArgTypes >
| Zips a series of vectors together. More...
class | fv::Map< Ret(ArgTypes...)>
| Maps a function over an input vector. More...
class | fv::Tuple< ArgTypes >

class | fv::DeTup< N, ArgTypes >
| Gets the Nth element from a tuple value. More...
class | fv::DeTupVector< N, ArgTypes >
| Creates a vector of extracting the Nth value from each entry in a vector of tuples. More...

# DESCRIPTION

This header defines a set of generic classes that wrap up "values". In essence, a Value<T> object is just something that contains a value of type T and can provide it when requested. The usefulness stems from composing values together with calculations. This enables very clear dependency mapping and a way to know clearly how every value was arrived at. This could be used to, for example, automatically generate commentary for plots that explain the exect calculation used to create it. Or easily making a series of plots contrasting different values that have been composed slightly differently.
