API breaking change. Implementation of Vibes params system in the drawBox function. Still needs to be implemented in other functions.
Orientation should be a number, not an array in ellipse drawing
messages.
Simplified C++ API code for variadic functions, and added convenience
macros for Matlab-style arguments passing.
Added axisAuto and axisLimits functions in C++ API.
