Make all paths relative

• Make paths for sequences, collection patch file and Pandora configuration relative to fix Make CLDReconstruction.py runnable from other directories #88

ENDRELEASENOTES

passes all our tests, but when you try to actually run the reconstruction from a different directory, it fails because of

CLDConfig/CLDConfig/PandoraSettingsCLD/PandoraSettingsDefault.xml

Line 100 in 691ef7e

<HistogramFile>PandoraSettingsCLD/PandoraLikelihoodData9EBin.xml</HistogramFile>

Handling this without creating a new file every time would need an extension of Pandora and its API to offer a copy of Pandora::ReadSettings that takes the XML as a string directly. Then we could dynamically rewrite the path from our side.

Can we do something even better, check in Python if this exists and fail otherwise? Countless of times I start running only to see that it fails when initializing Pandora, which is not too late but still

Great idea! We could already add a helpful error message now, I might add it tomorrow if I remember.

I tried, but how do you even get to that point? If I run it from somewhere else it already fails at the py_utils import...

I could change this PR to include the warning for Pandora, then stuff like tracking only should be runnable from anywhere and only when Pandora is needed it will warn.
