/*
The ParserItem class describes one item handled by the parser. A parser
item is the schema for parsing values from the deck, when configuring the
ParserItem *two* types are in action:
InputType: These are the types specified when instantiating a
ParserItem, the available types are currently: INT, DOUBLE, STRING,
RAW_STRING and UDA.
DataType: This the C++ type of items generated when parsing the deck,
currently the available datatypes are int, double, std::string and
the user defined type UDAValue.
Splitting the type treatment in two layers in this way enables
properties/transformations to be added to the data before they are
internalized as data in a DataType instance; e.g. the difference between
STRING and RAW_STRING is that for the latter quotes and '*' tokens are
retained.
