* split formatter into separated singleton classes
* split data engine matchers to classes
* nodiscard attribute for formatter methods
* small refactoring in matchers
* fix codefactor warnings
* fix test building
* massive changes inside includes, drop unused definitions
* rewrite some initialization methods to avoid additional
freeing/allocation
* drop some explicit destructors calls
Macros should be declared as `aw_macro<name,arg1,arg2,...>{{macro body}}` and then
they may be used as `aw_name<arg1,arg2,...>{{}}`. It just puts `macro
body` to pattern and replaces arguments to provided ones according to
macro call. E.g.:
```
$aw_macro<test,phrase>{{phrase}}$aw_test<hello world>{{}}
```
will transform into
```
hello world
```
* new tag - $tstime
* add summand parameter to float formatter
* drop version.h includes since it has been moved to awdebug.h (e.g. to
introduce BUILD_FUTURE guards easy in the future)
This commits series introduces bars which may be calculated from any
custom formula. For a start I've renamed $bar*tag to $bar* and add new
configuration parameters to graphical items.
No significant changes applied.
* function syntax has been changed to another one, any function may be called
by using the following construction:
$aw_function_name<some args here if any>{{function body if any}}
* rewrite travis.yml
