 Tutorial 1: Basic Python Integration

+This tutorial is meant to be a very basic introduction to interacting with the DREAM3D-NX underlying library called 'simplnx'. This
+tutorial will cover environment setup, minimal import statements and executing a few basic filters. Once you understand how to
+execute a filter, all filters are generally setup the same way. Use the search feature on the web site to find the filter 
+that you are interested in running.
