// C++ Interface: CKeyboard
//
// Description: Adds features like international keyboard layout mapping on top of the
// platform specific low level keyboard classes.
// Here it must be done only once. Within the other mentioned classes it would have to be done
// several times.
//
// Keyboards always deliver printable characters, logical keys for functional behaviour, modifiers
// ... alongside Based on the same hardware with the same scancodes (also alongside) but delivered
// with different labels to customers the software must solve the mapping to the real labels. This
// is done here. The mapping must be specified by an xml configuration that should be able to access
// everything available, but this allows for double/redundant or ambiguous mapping definition, e.g.
// ASCII/unicode could be derived from scancodes, virtual keys, modifiers and/or other
// ASCII/unicode.
