Newton code naming

[Sash]

Hello.

Just decided I really need better understanding of Newton details, so I have a question : what does mean
- m_ prefix for some variables
- d prefix for some internal types like dFloat, dVector, dMatrix ?

Are there some other conventions used for names ?

they are from my own convention I use for years.
m_ member variable of class
d data type.
