Data loading specification

[pfernique]

For a given Python interface of a StatisKit software component (e.g., StatisKit-Core), to load a data frame (e.g., data), an user must be able to type:

from statiskit import core
data = core.load_data("data")

For now, we consider:

• To save data according to the DSV format with:
  • headers in the first row,
  • the ; column separator,
  • the .dsv extension.
• To save data into a data directory at the root of the Python package tree (e.g., src/py/statiskit/core/data).
• That this data directory cannot be imported (e.g., from statiskit.core import data should raise a ImportError: No module named statiskit.core.data error)

To do so, a load_data function could defined in src/py/statiskit/core/_tools.py file.
Using a the __file__ variable of a __init__.py module file as input, this function should be able to load a data file from its basename prefix (e.g., use the input string "data" for loading the dataframe saved in the "data.dsv" file).
