Tutorial: Improve Step 1

* Update minimum required version to 3.10
* Use VERSION argument to project command rather than separate variables
* Replace `endif(USE_MYMATH)` with  more modern `endif()`
* Simplify the call to 'configure_file()'
* Add comments to tutorial.cxx to use as anchors in documentation
* Remove CMakeLists and TutorialConfig.h.in files that users should
  create. Consequently, remove Step1 from CMake tests.

 A Basic Starting Point (Step 1)
 ===============================
 
 The most basic project is an executable built from source code files.
-For simple projects, a two line CMakeLists file is all that is required.
-This will be the starting point for our tutorial. The CMakeLists file
-looks like:
+For simple projects, a three line CMakeLists file is all that is required.
+This will be the starting point for our tutorial. Create a ``CMakeLists.txt``
+file in the ``Step1`` directory that looks like:

+.. code-block:: cmake
+
+  cmake_minimum_required(VERSION 3.10)

+
+  # add the executable
+  add_executable(Tutorial tutorial.cxx)
 
-.. literalinclude:: Step1/CMakeLists.txt
-  :language: cmake
 
 Note that this example uses lower case commands in the CMakeLists file.
 Upper, lower, and mixed case commands are supported by CMake. The source
-code for ``tutorial.cxx`` will compute the square root of a number and
-the first version of it is very simple, as follows:
-
-.. literalinclude:: Step1/tutorial.cxx
-  :language: c++
+code for ``tutorial.cxx`` is provided in the ``Step1`` directory and can be
+used to compute the square root of a number.
 
 Adding a Version Number and Configured Header File
 --------------------------------------------------
@@ -40,55 +45,70 @@ The first feature we will add is to provide our executable and project with a
 version number. While we could do this exclusively in the source code, using
 CMakeLists provides more flexibility.
 
-To add a version number we modify the CMakeLists file as follows:
+First, modify the CMakeLists file to set the version number.

-Next let's add some C++11 features to our project. We will need to explicitly

+Next let's add some C++11 features to our project by replacing ``atof`` with
