Updated html documentation
Merge branch 'master' of https://github.com/SoFiA-Admin/SoFiA into HEAD
Added flagging and weights function
These changes add the options of data flagging and defining an analytic weights function into the pipeline and the user interface. The documentation is updated as well. The eval() function used for the weight function implementation is hopefully safe to use now thanks to implementation of a whitelist of allowed function names.
However, I would not recommend using the weights function option as it is currently implemented, because that implementation is affected by a number of Python-specific problems that could lead to unexpected behaviour, crashes of SoFiA, and in the worst case a freezing of your computer. All of the issues are commented in the source code (in import_data.py) and should be discussed and addressed before this code can be placed in a public release.
