Code update.

1.  Reformatted the make scripts and test units so that the code that
    generates the 'actual' and 'expected' test data is easier to read.
2.  Modified the make scripts so they produce test function reference
    data in a similar order.
3.  Removed semicolons from the end of code statements that do not
    result in command line output.
GET_DATA added.

1.  Added the function GET_DATA.
2.  Added the test unit TEST_GET_DATA.
3.  Added the script MAKE_GET_DATA.
4.  Added a project README file.
