introduce a value type abstraction to support custom column types (like temporal column types #21 )
Value types should provide the following methods:

read/write values to DataOutputStream
convert values to String
parse values from String

These value types must then be used in the following library parts:

CSV reader / writer
Automatic column type detection
Printer
Filter query parser

Value types are currently being worked on in branch
value-type-abstraction

Progress:

there are value types for all previously available columns.
value type object are available from column, row and header objects
CSV writer uses value types to write String representations
