Nicer Formatting

[pforero]

Currently the output is not well formatted. For example the output of methods returns the coding of regions and/or parties. A nicer output for the final user would be get the names instead of the codes.

An important thing to take into account is that these functions are used both for internal calculations and output. Coding is useful for the output of internal calculations. But names are better for the final user output. Not sure if maybe separate functions are needed for each case, or how best to do it.

Functions that need a nicer formatting:

election.mps()
election.parlament()
election.most_voted()

This can also be true for attributes, such as:

election.votes
election.parties /electoral_map
election.regions /electoral_map
election.distributon /electoral_map
