Teaser

We did some additional changes to the setup.py, now you can use `pip install teaser` to use TEASER in your python distribution.

Due to a mistake we needed to skip two version numbers, sorry for that! :-)

A new release of TEASER is available.

Notes:
- Better documentation
- bugfixes in the examples
- bugfixes in the project API

With this release we introduced **a lot of non-backwards compatible** changes, thus we highly recommend you to check your scripts using TEASER. There are probably two things you need to do:
1. all modules and packages are renamed to lower case (e.g. change import teaser.Project to teaser.project) to be PEP8 conform
2. If calculating simulation parameters, we do not longer support the parameter `calculation method`. If you want to use `vdi`please set the following parameters:

python
project.used_library_calc = 'AixLib'
project.number_of_elements_calc = 2
project.merge_windows_calc = True


If you want to use `ebc`

python
project.used_library_calc = 'AixLib'
project.number_of_elements_calc = 2
project.merge_windows_calc = False


Further features of this new release:
- beta release of the gui (it is not pretty, yet only works for AixLib and probably has some bugs, BUT it is a beginning :-) ) If you find any bugs or problems with the gui, please report them to us!
- import of CityGML files
- support of Annex60 model calculation
- lot of smaller features and bugfixes

Hard facts: more than 600 commits and about 80 closed issues.

**Please keep in mind, that this is still a pre-release. We are still working on the code and try to maintain it as good as possible. If you find any bugs or run into any problems using TEASER, please report this to us!**

- Bugfix in loading teaser xmls
- Bugfix in the parallel connection calculation
- Bugfix in the calculation method for RC-calculation

Bugfix for the export of the file naming of the modelica models. now only alphabetic characters and numbers are allowed. In addtion if a the filename starts with a number, an additional "B" for building is added to fix the error that modelica can not use this files.
