Modules

Here is a list of all modules:

Utilities.	The class template Array implements mult-dimensional arrays (mainly of integers and doubles)
Description of the physical space.	Each domain class are derived from the abstract class Domain
Spectral representation.	The fields are given, in each Domain, by a Val_domain objetcs
Physical fields.	Here are regrouped all the objects used to describe fields, without making reference to systems of equations
Metric handling.	They differ from the usual fields because they give access to many more methods (covariant derivatives, Ricci etc...) They are also more closely linked to systems of equations
Equations management	Are regrouped here the objects needed to solve systems of equations, like the Term_eq, the various operators, types of equations..
