logLevel compare bugfix

delete of dead code

tab to whitespace

bugfixes, reduandency removal, and docu

multilogger was logging to all it childs without checking there LogLevel in
relation to the LogLevel of the LoggerPayload.

Some constructors where redundant.

more examples and more documentation

some fixes

NullLogger and moduleName

wrong doc

I splitted the multi logger implementations out

loglevelF to loglevelf in order to make phobos style think writefln

document building

win makefile fixes

some optimizations thanks to @elendel-
some whitespace

some updates from the github logger project

* stdio- and filelogger now use a templatelogger base to reduce code

makefile fixes

makefile

fixed the unittest

made sure the stdiologger is set up at the end

some comment fixes

finding the filelogger segfault

closed another file

a lookup fix

darwin unittest fail output

more diagnostics

* more documentation for the templatelogger and multilogger
* it breaks the log function api
 * log and logf now behave as their write and writef counterparts
 * for logging with an explicit LogLevel call logl loglf
 * for logging with an explicit condition call logc logcf
 * for logging with an explicit LogLevel and explicit condition call
 * loglc loglcf
 * the log function with an explicit LogLevel like info, warning, ...
 * can be extended into c, f or cf and therefore require a condition
 * and/or are printf functions

something is still interesting

rebase and lazy Args

saver file handling

whitespace
