Heat transfer analysis is moved to its own package where the development continues. Two small modifications are needed for test files:
- Instead of `problem.properties.formulation`, we have two separate problems, `PlaneHeat` for two-dimensional problems and `Heat` for three-dimensional problems.
- Unnecessary prefixing of field names is changed. For example, now we simply have only "thermal conductivity" and not prefixed "temperature thermal conductivity".
A lot of code is moved to FEMBasis.jl regarding
calculating basis / shape functions of finite elements.
* add FEMBasis to REQUIRE
* remove obsolete files
* remove obsolete test files
* make integration point iterable
* loosen type definitions
* get length of element rather from basis than connectivity
* calculate midpoint of reference element
* wrong input argument to eval_basis! fixed
- Added TimerOutputs.jl to REQUIRE file
- JuliaFEM has now TimerOutput handle `to` and function `print_statistics()` to get summary of time and memory usage
- TimerOutputs is used in LinearSolver at the moment and tested in file `test_elasticity_2d_linear_with_surface_load.jl`
