update and fix example scripts doc page and mkdocs (#1533)
- update node scripts to be able to include them from real source that we will be able to test (next step to do). - new scripts are more user friendly. - add package.json for npm management of dependencies - update doc page - update mkdocs guide for potential issue on pip version with Python3 - update mkdocs-material theme (only bug fixes) Signed-off-by: Adrian Sutton <adrian.sutton@consensys.net>pull/2/head
