Flagged numerous peices of code that have local variables that are masking either member variables or variables scoped outside the current scope.

I've marked all the ones I found with the following TODO comment:

TODO: C6246: <blah blah>

a few in particular are the ones related to "oneShot" and "_target".  These are local variables that are declared that
mask either a method parameter or a member variable.
