Delay files

[Deleted user]

The delay functions are imported from libpic30.h which is a library from Microchip. This works fine, but the point is that FCY need to be defined before including the library, resulting in including System.h every time before including libpic30.h.
So it would be nice if there was a header file called Delay.h which does this and perhaps contains some more user friendly macros. The current macro for delay milliseconds for example is now __delay_ms() while it would be nicer to have a macro like Delay_ms() so Delay.h could contain such macros and wrap them to the Microchip library.
