Oxygen text added to each render.cpp file for the default projects. Text includes project explanation from Wiki, edited in places.

Empty project added as a default project.

Doxyfile updated. Each of the project locations added to INPUT configuration option. Consider just watching the whole project file so all new projects are automatically pulled through.

+Producing your first bleep!
+---------------------------
+
+This sketch is the hello world of embedded interactive audio. Better known as bleep, it 
+produces a sine tone.
+
+The frequency of the sine tone is determined by a global variable, `gFrequency` 
+(line 12). The sine tone is produced by incrementing the phase of a sin function 
+on every audio frame.
+
+The important thing to notice is the nested `for` loop structure. You will see 
+this in all Bela projects and in most digital audio applications. The first `for`
+loop cycles through the audio frames, the second through each of the audio
+channels (in this case left 0 and right 1). It is good to familiarise yourself
+with this structure as it is fundamental to producing sound with the system.
