New feature: ScalarArray. ScalarArrays are read-only 1D arrays containing max(mx, max(my, mz)) elements. ScalarArray is a new type of uniform and can be used for storing f.ex. forcing profiles. The DSL now also supports complex numbers and some basic arithmetic (exp, multiplication)

DSL now 'feature complete' with respect to what I had in mind before the summer. Users can now create multiple kernels and the library functions are generated automatically for them. The generated library functions are of the form acDeviceKernel_<name> and acNodeKernel_<name>. More features are needed though. The next features to be added at some point are 1D and 2D device constant arrays in order to support profiles for f.ex. forcing.

The previous attempt (dsl_feature_completeness_2019-08-23) to enable arbitrary kernel functions was a failure: we get significant performance loss (25-100%) if step_number is not passed as a template parameter to the integration kernel. Apparently the CUDA compiler cannot perform some optimizations if there is a if/else construct in a performance-critical part which cannot be evaluated at compile time. This branch keeps step_number as a template parameter but takes rest of the user parameters as uniforms (dt is no longer passed as a function parameter but as an uniform with the DSL instead).

User config param overhaul complete, works. If I haven't missed anything, all fields and user parameters, and everything related to simulation can now be declared with the DSL. The only thing that you need to do is to fill the declared symbols with data, like with OpenGL and GLSL.

Moved STENCIL_ORDER and NGHOST out of user-defined parameter as these are actually internal defines used to configure the built-in functions. Additionally, renamed all explicitly declared uniforms from dsx -> AC_dsx in the DSL in preparation for having clear connection between DSL uniforms and the library parameter handles created by the user (AcRealParam etc)

Made the DSL syntax less confusing: Input and output arrays are now ScalarField and VectorFields instead of scalars and vectors. C++ initializers are now also possible, removing the need to declare Fields as int or int3 which was very confusing, like "what, you assing an int value to a real, what the &^%@?"
