\class vpMomentBasic
\ingroup group_core_moments
\brief This class defines the 2D basic moment \f$m_{ij}\f$.
This class is a wrapper for vpMomentObject wich allows to use it as a moment.
This enables all common operations such as adding to a vpMomentDatabase.
In the case of a dense object \e O, 2D basic moments are defined by:
\f[m_{ij} = \int \int_{O} x^j y^j dx dy\f]
In the case of a discrete set of \e n points, the basic moments are defined by
\f[m_{ij} = \sum_{k=1}^{n} x_k^j y_k^j \f]
The selection of a dense or discrete object is done in vpMomentObject.
The maximum order of vpMomentBasic is the same as that of vpMomentObject (ie: \f$i+j \leq \f$ vpMomentObject::getOrder).
Note that in the continuous case, the basic moment \f$m_{00}\f$ corresponds to the surface \f$a\f$ of the object.
In the discrete case, it is the number of discrete points \f$n\f$.
