tagged_logger changelog

Version 0.2.5

If somebody is not ready to define any logging rules, but still want to use #logger() everywhere:
```
  TaggedLogger.init
```
Runs about 3 times faster by executing code responsible for rule matching on the first #logger() call and "precompiling" it. So rather than iterating over all rules on every #logger call only subset of rules specific to #logger() callee get executed.
Code simplified

The DSL for defining rules is changed - instead of

  output /A/ => ...

use one of:

  debug /A/, :to => ...
  info  /A/, :to => ...
  warn  /A/, :to => ...
  error /A/, :to => ...
  fatal /A/, :to => ...

and instead of

  output /A/ do
    #...
  end

use

  debug /A/ do #or #info, #warn, #error, #fatal
    #...
  end

These rules are more specific since they name logging level explictly which makes DSL shorter, also such form has allowed to make some optimization.

The #format() could be used inside rules block:

  TaggedLogger.rules do
    format { |level, tag, msg| "#{level}-#{tag}: #{msg}\n"}
    info /.*/, :to => Logger.new(STDOUT)
  end
