Detailed Description

Producer of a JetTagCollection where tag is defined as # of pixel tracks in a tau-style isolation cone centered around jet direction. Notes:

we don't care if signal tracks exist or not (protection against pixel inefficiency).
Only tracks that belong to the primary vertex are considered.
If primary vertex doesn't exist, tau jets are tagged as perfectly isolated.
