Transition to CallByName

[timhall]

For compatibility purposes, CallByName is much more suitable than Application.Run (only available in Excel as far as I know). I propose switching from LogCallback to LogInstance and then using CallByName LogInstance, "Log", ....

Problem with CallByName is that it only calls methods in objects i.e. class modules which makes it both more limited and more complicated to use.
