Allow column names to be aliased

[jangeador]

Another suggestion is to implement the ability to alias columns. The .csv that I have to work with sometimes come with crappy column names. It would be nice if we could alias the column so that they will match the header when we define it, but we can use a different column name after that.

For example:

COLUMNS_1 = [
    {'name': 'Fiscal Year', 'required': True, 'alias': 'fiscal_year'},
    {'name': 'Month', 'required': False},
    {'name': 'Fund', 'required': False},
    {'name': '%exp', 'required': False, 'alias': 'percent_expended'},
    {'name': 'Unexpended Budget', 'required': False},
    {'name': 'Encumbrance', 'required': False},
    {'name': 'Unencumbered Budget', 'required': False},
    {'name': '%unenc', 'required': True, 'alias': 'percent_unencumbered'},
    ]

I would like to help, but I don't quite understand how to implement these well enough. Let me know if you would like to give me directions on how to do it and I will give it a try.
