Given this spreadsheet:
| Name | Uniform Number | Birth Year | Games Played | Goals | Assists |
| Bobby Orr | 4 | 1948 | 657 | 270 | 645 |
| Wayne Gretzky | 99 | 1961 | 1487 | 894 | 1963 |
| Mario Lemieux | 66 | 1965 | 915 | 690 | 1033 |
to_dictionaries_using_headers_as_keys should return a list with 3 single list dictionaries, one for each non-header row. The dictionaries would be filled with entries for each column, using the cell in the header of the column as the key and the cell in the particular row of the column as the value.
[ { TEXT("Name") => TEXT("Bobby Orr"), TEXT("Uniform Number") => INTEGER(4), TEXT("Birth Year") => INTEGER(1948), TEXT("Games Played") => INTEGER(657), TEXT("Goals") => INTEGER(270), TEXT("Assists") => INTEGER(645) },
{ TEXT("Name") => TEXT("Wayne Gretzky"), TEXT("Uniform Number") => INTEGER(99), TEXT("Birth Year") => INTEGER(1961), INTEGER("Games Played") => INTEGER(1487), TEXT("Goals") => INTEGER(894), TEXT("Assists") => INTEGER(1963) },
{ TEXT("Name") => TEXT("Mario Lemieux"), TEXT("Uniform Number") => INTEGER(66), TEXT("Birth Year") => INTEGER(1965), INTEGER("Games Played") => INTEGER(915), TEXT("Goals") => INTEGER(690), TEXT("Assists") => INTEGER(1033) } ]
NOTE: you can assume that you will not be passed the empty list. If you want to handle this case anyway, raising Empty seems like a reasonable thing to do.
