GDP: Renaming NR 3

[Trevor Daniels]

Chapter 3 in the Notation Reference is currently named "Input syntax", but 
the contents in the latest revision of the 2.11 docs are much wider than the 
name implies and I'd like to change it.  The trouble is, the contents are 
rather diverse, being mainly the left-overs from chapters 1 & 2. 
Suggestions very welcome!

[John: hang on with the translations until we decide this!]

Here's an outline of the current contents of the NR:

1. Musical notation
2. Specialist notation
3. Input syntax
    Input structure
    Useful concepts and properties
    Titles and headers
    Working with input files
    Controlling output
    MIDI output
4. Spacing issues
5. Changing defaults
6. Interfaces for programmers

Possibilities:

3. General notation
3. Further notation
3. General concepts
3. General notation and concepts
3. Non-musical notation
3. Miscellaneous topics

Another more radical alternative would be to move "Useful concepts and 
properties" into Chapter 5, leaving just input and output topics in Chapter 
3, which could then be re-organised as:

3. Input and output files [or some such name]
    Input structure
    Working with input files
    Titles and headers
    Controlling output
    MIDI output

Would this be better?  What might this be called?
