Gyselalib++ tests

The tests folder contains the tests of the different elements implemented in the src folder. It is broken up into the following sub-folders:

• advection - Tests on the advection operators made for templated dimensions.
• data type - Tests for the templated data types.
• geometry5D - Tests in the 5D geometry.
• geometryRTheta - Tests in the polar geometry.
• geometryVparMu - Tests in the vpar-mu geometry.
• geometryXVx - Tests in the x-vx geometry.
• geometryXYVxVy - Tests in the x,y-vx,vy geometry.
• math_tools - Test for mathematical functions.
• MPI parallelism - Tests for the templated MPI operators.
• multipatch - Tests for the classes that work over multipatch geometries.
• PDE solvers - Tests for the templated Partial Differential Equation solvers.
• quadrature - Tests for the templated quadrature operators.
• timesteppers - Tests for the templated time stepping operators.
• utils - Tests for general utilities.
