Scala macros to have fluent copy on case classes

```sbt

libraryDependencies += "com.github.geirolz" %% "fluent-copy" % "0.0.1"

```

- `copyWith` when `true` adds a method `with$FIELD_NAME(newvalue: $FIELD_TYPE): $CASE_CLASS`.

- `update` when `true` adds a method `update$FIELD_NAME(f: $FIELD_TYPE => $FIELD_TYPE): $CASE_CLASS`.

- `collection` when `true` adds methods:

    - For `Option`

        - `withSome$FIELD_NAME(f: $FIELD_COLLECTION_TYPE): $CASE_CLASS`

        - `withNone$FIELD_NAME: $CASE_CLASS`

    - For collections `Seq`, `List`, `Set`

        - `withOne$FIELD_NAME(f: $FIELD_COLLECTION_TYPE): $CASE_CLASS`

        - `withEmpty$FIELD_NAME: $CASE_CLASS`

```scala

import com.geirolz.macros.fluent.copy.FluentCopy

@FluentCopy(copyWith = true, update = true, collection = true)

case class Foo(

  value: Int,

  option: Option[Double],

  list: List[String],

  set: Set[String],

  seq: Seq[String]

)

```

Generates

```scala

implicit class FooFluentConfigOps(i: Foo) {

  def withValue(value: Int): Foo = ???

  def updateValue(f: Int => Int): Foo = ???

  def withOption(option: Option[Double]): Foo = ???

  def updateOption(f: Option[Double] => Option[Double]): Foo = ???

  def withSomeOption(option: Double): Foo = ???

  def withNoneOption: Foo = ???

  def withList(list: List[String]): Foo = ???

  def updateList(f: List[String] => List[String]): Foo = ???

  def withOneList(list: String): Foo = ???

  def withEmptyList: Foo = ???

  def withSet(set: Set[String]): Foo = ???

  def updateSet(f: Set[String] => Set[String]): Foo = ???

  def withOneSet(set: String): Foo = ???

  def withEmptySet: Foo = ???

  def withSeq(seq: Seq[String]): Foo = ???

  def updateSeq(f: Seq[String] => Seq[String]): Foo = ???

  def withOneSeq(seq: String): Foo = ???

  def withEmptySeq: Foo = ???

}

```
