"""Beginnings of a script to filter logcat. Eventually I'd like a UI
|

|
|
like what's built into AS or apparently available on the Mac, where
|
||
|
|
individual tags, threads and and processes can be viewed clicking
|
||
|
|
buttons or dropdowns. For for now, just a commandline app that watches
|
||
|
|
for app startup and then prints everything with its PID.
