Update of the BEM code in order to be able to deal with multiple meshes and order 2 elements. The code is however not able to deal with a line inside the domain that has been assigned a boundary condition.

main and CMakeList in order to start the coupling. The BEM solver already returns the electrostatic pressure for each boundary element.

Functional BEM code divided into functions, with the element geometric parameters stored inside the element struct and the 'ElementData' visualisation.

Boundary part: change from elementMap to elementVector; Domain part: rough/basic implementation for testing
