Snippet Analysis Helper

## Description
This is a page to help us analyze the validity of a snippet. It is under the URI '/testing/analyze'. The more valid snippets that you put into the system, the better the analysis is. This is because each snippet digraphs are put into the database when they occur so probabilities can be formulated. Currently the data is stored in their own tables, but they can be integrated into the existing snippet table when we decide the analysis is valid.
