Logging syntax

All the usual methods are implemented with string interpolator:

There are basic methods:

• info"This is INFO message
• warn"This is WARN message
• debug"This is DEBUG message
• and so on.

And there are methods with errors:

• errorCause"Oh no, an error!"(error)
• warnCause"Well, an error!"(error)
• infoCause"It's fine, just an error!"(error)
• and so on.

One can add more information to the log structure of the message with these methods:

• infoWith"I got data!"("key" -> "skeleton", "value" -> "too much", "price" -> 0)
• errorWith"I got data!"("key" -> "skeleton", "value" -> "too much", "price" -> 0)
• and so on.
