The new system defines specific functions:
- TUM.Logger.trace
- TUM.Logger.debug
- TUM.Logger.info
- TUM.Logger.warn
- TUM.Logger.error
These function can be passed any number of arguments additionnally to the message, and they'll safely format these arguments to be passed to `string.format`.
Example of use:
`TUM.Logger.trace("function DCSEx.world.setUnitLifePercent(unitID=%s, life=%s)", unitID, life)`
Parameters are formatted based on their type (tables are fully printed for example),
This is a reduced port of the VEAF logging system, which has been used for years.
