   Adds support for temporals (and subclasses) to the Accord DSL.

   Adds support for temporals (and subclasses) to the Accord DSL.

   Usage

   To use these extensions, import this package as follows:

   import java.time.LocalDateTime
   import java.time.temporal.ChronoUnit
   import java.time.Duration
   
   case class Person( name: String, birthDate: LocalDateTime )
   
   // Import the Accord DSL and Java 8 extensions...
   import com.wix.accord.dsl._
   import com.wix.accord.java8._
   
   // LocalDateTime (and other temporals) are now supported
   implicit val personValidator = validator[ Person ] { p =>
     p.name is notEmpty
     p.birthDate is before( LocalDateTime.now )
   }

   Combinators

   Supported operations:

   // Simple equality/inequality
   val lastYear = LocalDateTime.now.minus( 1L, ChronoUnit.YEARS )
   p.birthDate is equalTo( lastYear )
   p.birthDate is notEqualTo( lastYear )
   
   // Equality with tolerance (both variants are equivalent)
   val oneWeek = Duration.ofDays( 7L )
   p.birthDate is within( oneWeek ).of( lastYear )
   p.birthDate is within( 7L, ChronoUnit.DAYS ).of( lastYear )
   
   // Before/after
   val ageOfAdulthood = LocalDateTime.now.minus( 18L, ChronoUnit.YEARS )
   p.birthDate is before( ageOfAdulthood )
   p.birthDate is after( ageOfAdulthood )
   
   // Arithmetic-style operations
   p.birthDate must be <= ageOfAdulthood
   p.birthDate is between( lastYear, LocalDateTime.now.minus( oneWeek ) )
