The multifile module

In order to break our current lib.rs file down, we are going to have to change how we declare modules.

The source for this section is in Chapter10/MathsLibMultiFile and Chapter10/MathsLibMultiFileDirs.

Currently, we have this:

mod Trigonometry // top level module 
{ 
    mod Natural  // sub module 
    {  
    } 
     
    mod Arc      // sub module 
    {  
    } 
} 

To break this into separate files, we need to declare only the top-level modules in lib.rs:

mod Trigonometry; 
mod RegressionAnalysis; 
mod Conversions; 
mod Bases;
