> ExcelReader needs an ability similar to CSVReader to "Use String Fields From
> Header" as a Schema Access Strategy.
> Current implementation has:
> 1. Use Schema Name/Schema Text - this option relies on the order of the
> columns. Possible issues - order of the columns change, but types dont. This
> cause further calculations to be erroneous.
> 2. Infer Schema - replaces real column names with column_1,column_2 etc -
> this again loses the "context" of the column and forces us to rely on how
> columns are ordered.
> Any workarounds make workflow more complicated.
