Introduce method to add analysis results

We'd like to improve MRVA query gists by giving them more descriptive
titles that contain useful information about the query.

Let's add the number of query results to the title of the gist.

To do this we'll first need to count all the results provided to us in
the `analysisResults` array. There is an item in this array for each of
the repositories we've queried, so we're introducing a method to sum up
results for all the items in the array.
