Accuracy analysis of the results of tests

Here we can discuss our conclusions about the accuracy of the results obtained from each test.
### Passed Tests

List of tests for which the results accuracy is as expected for the formal order of the numerical scheme employed:
- [ ] Lorenz' test:
- [ ] explicit:
- [ ] Adams-Bashforth;
- [ ] Euler;
- [ ] Leapfrog;
- [ ] Runge-Kutta:
- [ ] TVD/SSP;
- [ ] Low Storage;
- [x] Oscillation test¹:
- [x] explicit:
- [x] Adams-Bashforth;
- [x] Adams-Bashforth-Moulton;
- [x] Euler;
- [x] Leapfrog;
- [x] Runge-Kutta:
- [x] TVD/SSP (5 stages solver seems **less acurate** than the similar low storage 5 stages);
- [x] Low Storage;
- [x] embedded³;
- [ ] Burgers' test:
- [ ] explicit:
- [ ] Adams-Bashforth;
- [ ] Euler;
- [ ] Leapfrog;
- [ ] Runge-Kutta:
- [ ] TVD/SSP;
- [ ] Low Storage;
- [x] 1D Euler test²:
- [x] explicit:
- [x] Adams-Bashforth;
- [x] Euler;
- [x] Leapfrog;
- [x] Runge-Kutta:
- [x] TVD/SSP;
- [x] Low Storage;
### Issues
1. Analysis completed: all solvers works as expected.
2. Analysis not completed.
3. It is necessary to define a methodology for measuring the accuracy of adaptive time step schemes.
