Interface LogMethods

    Loxer.log('Hello World');

• it is cached until the logger is initialized
• it won't proceed any output if Loxer is disabled
• the output will be streamed out to the LoxerOptions.callbacks declared in Loxer.init(options)
• if no callbacks are given at the initialization, all logs will be logged with console.log(message, item), but only in development mode
• can be chained with .highlight().log(...) or .h().log(...) to highlight the log
• can be chained with .level().log(...) or .l().log(...) to set a level to the log - otherwise it's 1 (high)
• can be chained with .module().log(...) or .m().log(...) to assign a module to the log - otherwise it's NONE
• all functions can be chained in combination and different order like: Loxer.h().l(2).m('Account').log(...)

    Loxer.error(new Error('Goodbye World!'));

• it is cached until the logger is initialized
• it won't proceed any output if Loxer is disabled
• the errors will be streamed out to the LoxerOptions.callbacks declared in Loxer.init(options)
• if no callbacks are given at the initialization, all errors will be logged with console.log(error), but only in development mode
• the given Error will be appended to the output error
• if the message is of type string | number | boolean | object, then a new Error(message.toString()) will be created and appended
• all opened logs that were not closed until the error occurred will be appended to the error outputLog
• a history of logs will be appended if enabled
• can be chained with .module().error(...) or .m().error(...) to assign a module to the error - otherwise it's NONE
• chaining with .highlight().error(...) or .h().error(...) does not color the message differently but append the stack to the default console output
• chaining with .level().error(...) or .l().error(...) will not take any effect on the error log (except that level will be a property of the output)

    const loxId = Loxer.open('Open World!')

• the log will get a box layout.
• it returns an id (typeof number) that can be used with Loxer.of(id) to assign other logs to it
• it is cached until the logger is initialized
• it won't proceed any output if Loxer is disabled
• the output will be streamed out to the LoxerOptions.callbacks declared in Loxer.init(options)
• if no callbacks are given at the initialization, all logs will be logged with console.log(message, item), but only in development mode
• can be chained with .highlight().open(...) or .h().open(...) to highlight the log
• can be chained with .level().open(...) or .l().open(...) to set a level to the log - otherwise it's 1 (high)
• can be chained with .module().open(...) or .m().open(...) to assign a module to the log - otherwise it's NONE
• all functions can be chained in combination and different order like: Loxer.h().l(2).m('Account').open(...)

    // this has to be done before:
    const id = Loxer.open('opening message');
    // assign a log:
    Loxer.of(id).add('next step is reached');
    // assign an error:
    Loxer.of(id).error('something went wrong');
    // close the log box:
    Loxer.of(id).close('closing message');

• assigned logs / errors will receive a time consumption since the box was opened
• it won't proceed any output if Loxer is disabled
• can be chained with .highlight().log(...) or .h().log(...) to highlight the log TODO level changes
• can be chained with .level().of(...) or .l().of(...) to set a level to the logs - otherwise it's 1 (high)
• chaining with .module().of(...) or .m().of(...) to assign modules will take no effect though assigned modules will always adapt the module of the opening log
• all functions can be chained in combination and different order like: Loxer.h().l(2).m('Account').log(...)

• add: (message: string, item?: any) - assigns a single log to the box
• error: (error?: Error | string) - assigns an error log to the box
• close: (message: string, item?: any) - assigns a log to the box, that also closes the box (and its box layout)
• ATTENTION: calling add(), error() or close() after closing the box, the log will not be appended to the box but logged anyways with a Warning
