Comparison of models and tableau SQLs

[esenilsson]

Thanks for a great repo!

I have an issue where my model names are not in lower(), and don't get any matches between tableau and dbt.

When i change the following (in query_parsing.py)

for model in models.keys():
    if model in query:
        found[model] = models[model]

to

for model in models.keys():
    if model.lower() in query:
        found[model] = models[model]

it works fine. I was not able to do a pull request however.
