object StringParser
Parsing methods from String to various simple types.
Contains parsers for common types, like numbers, dates and times.
Additional parsers may be provided by implementing StringParser or FormattedStringParser traits
and putting implicit values in scope.
StringParser may be implemented if there are no different formatting options for given type, e.g. for integers
(although one may argue if this is a good example). For all cases when different formatting options exist,
FormattedStringParser should be implemented.

Type Members
- class Pattern[A] extends AnyRef
Intermediary to delegate parsing to in order to infer type of formatter used by parser.
Intermediary to delegate parsing to in order to infer type of formatter used by parser.
When adding parsing function to an entity, instead of providing
def parse[A, B](input: A, format: B)(implicit parser: FormattedStringParser[A, B]): ParseResult[A]
which requires then to use it as
entity.parse[Double, NumberFormat]("123,45", numberFormat)
one can provide function to get this
Patterndef parse[A]: Pattern[A]and use it with nicer syntax
entity.parse[Double]("123,45", numberFormat)
- A
target type for parsing
