The Curve comparison is possible through R-Factor analysis.
Further comparison like shape analysis, similarity index... will
be included later.
Data export is now possible through the gui menu or as a method of
the Data object.
F2PY can generate inconsistent suffix for *.so files due to a
different version of numpy if not the same as the one used
in the virtualenv. The workaround is to remove the
"cpython-36m-x86_64-linux-gnu"-like part of the name. The import
mechanism works well without. This is a tiny hack though.
