Spreadsheet To Dictionaries Assignment

Follows Spreadsheet and Chained Dictionaries exercises.

Inspiration

The aggressively helpful Ruby libraries which support CSV parsing to hashes with headers as keys.

Code To Implement

structure SpreadsheetToDictionaries

to_dictionaries_using_headers_as_keys

fun to_dictionaries_using_headers_as_keys(s : sheet) : (cell,cell) SingleListDictionary.dictionary list =
       raise NotYetImplemented

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.
