Detailed Description

Class containing the Model Information describing the formal Spatial (or Temporal) Characteristics of the (set of) random variable(s) under study.

The Model is essentially a container with two main contents:

the covariance part: see ACov.hpp for more information
the drift part: see DriftList.hpp for more information

The additional member CovContext only serves in carrying the following information:

the number of variables: if more than 1, the Model becomes multivariate
the field extension: this information is needed to get a stationary version to any covariance
the experimental mean vector and the variance-covariance matrix (used to calibrate the Model)
