Info, Debug, Warn and Excep will format ouputs separated by a `;` when args are passed
`notify_waiting` is a new function that letting you know some process is running for an unknown amount of time
optional `delay` during `shutdown_current_notebook`
Info, Debug, Warn and Excep will all have `X_mode` and `in_X_mode` functions much like in_debug_mode and debug_mode
`__init__` will auto pull from logger now
Better non-linear `Timer` (and `Report` and `track2`)
