Detailed Description
template<typename T>
class fv::ObservedValue< T >
A generic, observed, value.
An ObservedValue is the interface to your dataset. Upon creation, an ObservedValue is given a pointer to an object of type T. When an observation is loaded into memory, the value at the location referenced by that pointer must be updated with the associated data from that observation. This is the responsibility of whatever DataSet implementation is being used. This object then will read that data and return it when requested.

§ _reset()

Mark the internal value as invalid.
This is needed for DerivedValue to force a recalculation of the internal value when a new observation is loaded into memory. It is called automatically for all GenValue objects when reset is called.
Implements fv::GenValue.
