Test 3D camera

 Goals are: parsing an IGC file containing flight data, giving analytics about the flight, and if I really have time to kill, making some kind of (3D??) view of the flight..
 
-# Dependencies
+TODO:
+- convert sexagesimal (deg/min/sec) coordinates to decimal degrees
+- convert decimal degrees to cartesian (x, y, z) coordinates
+- choose scale to represent X meters as Y world units
+- get those new units (cartesian & world units) as data fields in the doubly linked list (so we can print GPS coords & draw 3d points using the same data structure)
+- draw points in the 3d world
+- draw lines between these points
+- make camera controls: N for Next, P for Previous
+- Text information: average horizontal/vertical speed etc.
+- Plane mesh
+- Ground texture

+## Dependencies
 
 These are mainly for building the project, and for Raylib (the 3D graphic library):
