ColumnDefinitions

for cypher file why does neo4j have 4 different ways to import a CSV, out of which only one works, and really the only help we get is a csv file reader, and we need to specify exactly how each column needs to be parsed and mapped...?

for header file

for data file updates our internal _columnDefByPropertyName model with type information based on runtime values, so that we later have all metadata required for the header file
