/*
* Contains methods for evaluating a definite integral of a function R2 -> R defined on a rectangular domain with a
* regular subdivision (all cells are the same).
*
* Input : - Function object with f : R2 -> R (vector of two double in input
* and a double in return)
* - Domain object with a boundaries vector with 2 vector of 2 double
* each
* - Method object with the name of the integration method to use :
* - "Midpoint"
* - "Trapz"
* - "Simpson"
* Contains the following methods : - IntegrationMidpoint() - Integration method that return a result as
* as a double
* - IntegrationTrapeze() - Integration method that return a result as
* as a double
* - IntegrationSimpson() - Integration method that return a result as
* as a double
* - GetResult() - Return the result value of the solver
