  DemoReqs ----> DateTime         references static library
           ----> FileSystem       references static library
           ----> CodeUtilities    includes header only
           ----> SingletonLogger  includes header only
           ----> StringUtilities  includes header only
           ----> TestUtilities    includes header only

- The Application (startup) project is DemoReqs.
- DemoReqs makes references to DateTime and FileSystem
  - Those projects are built as static libraries with their mains disabled
- DemoReqs uses header files from CodeUtilities, SingletonLogger,
  StringUtilities, and TestUtilities.
  - All of these projects are built as console executables with mains enabled.

This is a typical implementation pattern for me.  
- Small utilities have all of their functionality in their header files (*.h),
  using class declarations and inline methods (inline in header but not in class).
  - That allows applications to use them without including their libraries
    or implementation files (*.cpp).
- Larger utilities declare their functionality in their header files and
  and provide their implementation in implementation files.  They are built
  as static libraries, with mains disabled, and the Application project makes
  references to them.

To build this solution:
- Right-click on each static library project (DateTime and FileSystem) and
  select build.
- Right-click on solution and build.
- If you start by building the solution, that will fail if the Application 
  project references a library project that hasn't been built yet.  It should
  succeed if you build again.
- If you use the configuration manager for each project - available from the
  properties dialog - and set the dependencies appropriately, then builds will
  always succeed, provided that the code itself compiles successfully.
