Identify Serial COM devices by friendly name in Windows

Uses Windows registry information to ID Serial COM devices

This function scans the Windows registry in two places and associates active COM ports with their registered "Friendly Name". The function returns an N x 2 cell array where N is the number of active COM ports. The first column contains the friendly names of the devices where they exist and the second contains their COM number. If no devices with friendly names are found, devices is empty.

This function is not necessarily optimized but it is my solution to identifying serial devices connected by virtual COM port in Windows without having to query every device. If multiple devices with the same friendly name are connected to the computer, the output will contain both devices with their COM ports but they will be otherwise indistinguishable by this function.
