*: normalize usage of layouts before, I used them two ways, once was by setting the layout later by using setLayout(QWidget), and the other was just using the constructor. I find the constructor to be easier to read, so I chose that one.

#ifndef __core__array_h
#define __core__array_h

#ifndef ARRAYSIZE
#	define ARRAYSIZE(x) (sizeof(x) / sizeof(x[0]))
#endif

#endif // __core__array_h
