At this moment only the (by NAIF considered) most cruicial
c_spice API's have been covered, such as getting state vectors
from one reference frame to another, simple time conversions,
load/unload of single and multiple kernels etc. All of which as
described in:
http://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/info/mostused.html
Also added linker flag to except the LIBCMTD.lib as it caused conflicts
on Windows.
- Made the BASE_PATH variable relative to the binary, correctly set
using the CMake provided path to the project folder
- Fixed SceneGraphNode tests using std::string and Dictionary creation
using intermediate Dictionaries.
- Moved all OpenSpace headers to separate include directory
- Added OpenSpaceTests binary with OPENSPACE_HAVE_TESTS define
- Added CMake setting of BASE_DIR
- Added OpenSpace initial tests for SceneGraph and SceneGraphNodes
- Added OpenSpace initial tests for psc and pss
- Restructured OpenSpace so no GL functions are called in constructors
to make the classes testable
- Todo: Make the base dir possible to set through command line argument
and configuration file
