Write a function: convertDol(D): that converts from a Dictionary of Lists representation in D to the equivalent List of Lists representation, returning both the list of column names, as given by the keys of D, as well as a list of lists storing the data in the values of D. Note that, because we do not know the order of mappings in a dictionary, the order of fields in the column names, and the order of fields in the rows of the data set may not be apparent. But as long as all rows as well as the list of column names is consistent, the conversion is valid. Hint: a list comprehension might come in handy.
