Declared in `<ball_loggermanager.h>`

Create a scoped guard that will create the logger manager singleton having the specified `configuration` of defaults and attributes. Optionally specify a `globalAllocator` used to supply memory. If `globalAllocator` is 0, the currently installed global allocator is used. This method has no effect (aside from logging a warning) if the logger manager singleton already exists. Note that on destruction, this scoped guard will destroy the logger manager singleton, if the singleton exists at that time.

Create a scoped guard that will create the logger manager singleton having the specified `observer` that receives published log records and the specified `configuration` of defaults and attributes. Optionally specify a `globalAllocator` used to supply memory. If `globalAllocator` is 0, the currently installed global allocator is used. This method has no effect (aside from logging a warning) if the logger manager singleton already exists. The behavior is undefined if `observer` is 0, goes out of scope, or is otherwise destroyed. Note that on destruction, this scoped guard will destroy the logger manager singleton, if the singleton exists at that time.
