Added an example for creating arbitrary projects, see acc/test_solver and src/exampleproject. Note: make sure that dt is calculated adequately and that all parameters are defined properly (see src/exampleproject/simulation.cc)

+// Currently the built-in functions (derx, derxx etc) are defined in CUDA in integrate.cuh.
+// This is bad. Instead the built-in functions should be defined in the DSL, and be "includable"
+// as a standard DSL library, analogous to f.ex. stdlib.h in C.
