'aparse_s is a generic function used to extract and parse a field from a stanza and cast it to a value. ?default assign a default value if the field is absent. The function raise ParseError if ?required is true ( default false ) and the field is absent and no default is given. parse_s gets a parsing function, a label and a stanza and returns the value associated to the label.
val get_field_value :
parse:(string -> Dose_common.Format822.stanza -> 'a) ->
par:Dose_common.Format822.stanza ->
field:(string * 'a option) ->
string * 'aget_field_value is a generic function used to extract and parse values from a Format822.stanza. It gets a parsing function parse, a stanza par and a tuple field where the first element is the label associated to the value to be parsed and the second element is a parsed value. If the parsed value is not none, the the function returns it directly together with the associated label. Otherwise the function will use the parsing function to extract the value from the stanza. This function is used to initialize a package object with certains defaults values without parsing the entire stanza.

option) -> Dose_common.Format822.stanza -> object ... endRepresentation of a PEF package. This object gets a stanza (a list of list of fields) and return a pef object. Each field can be directly initialized using the optional arguments, providing the name of the field and an optional value. If the value is None, then the value is computed by parsing the corresponding field in the 822 stanza. Otherwise, the field is initialized using the given value (and ignoring the value in the 822 stanza).
