<br>
It was not possible to also move base/spline out, because it uses<br>
base/Eigen.h which is defined in base/types (direct cyclic include). So<br>
the new library is now called base/logging, as only logging is included<br>
there (and Singleton.hpp which is used by the logging).<br>
<br>
I left backward compability headers for logging in base/types.<br>
<br>
As we currently also discuss whether base types should stay header only,<br>
I guess we can wait for that outcome until we decide on base/Spline.<br>
<br>
<br>
What's left is to do:<br>
<br>
1. transfer the ownership of <a href="https://github.com/planthaber/base-logging" rel="noreferrer" target="_blank">https://github.com/planthaber/base-logging</a><br>
to rock-core<br>
<br>
2. Merge <a href="https://github.com/rock-core/package_set/pull/79" rel="noreferrer" target="_blank">https://github.com/rock-core/package_set/pull/79</a> to define the<br>
base-logging package<br>
<br>
Now the package is defined (no build impacting changed until now).<br>
<br>
3. Actually make base/types use the new library:<br>
<a href="https://github.com/rock-core/base-types/pull/80" rel="noreferrer" target="_blank">https://github.com/rock-core/base-types/pull/80</a><br>
<br>
4. make base/console_bridge dependent on base-logging instead of base/types<br>
<a href="https://github.com/rock-core/base-console_bridge/pull/2" rel="noreferrer" target="_blank">https://github.com/rock-core/base-console_bridge/pull/2</a><br>
