+package org.geoscript.feature
+
+/**
+ * Utilities for working with [[org.geoscript.feature.Feature]] in a typesafe way.
+ *
+ * [[org.geoscript.feature.Feature]] is defined in terms of java.lang.Object and
+ * requires casting to use. The classes in this package provide some
+ * convenience around doing the casting - in particular, we define a trait
+ * [[Fields]] which can be used to retrieve and update fields from and to
+ * features.
+ *
+ * A ``Fields`` may be constructed from a name and a type. The Fields then provides
+ * an ``unapply`` method for extracting values from features, and an update
+ * method for updating a feature (in place.) This enables pattern-matching with
+ * fields instances, and use of scala's syntactic sugar for updating
+ * collections. (By convention, fields instances should have names with an
+ * initial capital for use with pattern matching.)
+ *
+ * {{{
+ * val feature: Feature
+ * val Title: Fields[String] = "title".of[String]
+ * Title.unapply(feature): Option[String]
+ * val Title(t) = feature
+ * Title.update(feature, "Grand Poobah")
+ * Title(feature) = "Grand Poobah"
+ * }}}
+ *
+ * Fields instances may be combined by use of the ``~`` operator. In this case,
+ * the primitive values used with the Field must also be combined or
+ * deconstructed using ``~``.
+ * {{{
+ * val Record: Fields[String ~ Int ~ String] =
+ * "title".of[String] ~ "releasedate".of[Int] ~ "artist".of[String]
+ * val Record(title ~ releaseDate ~ artist) = feature
+ * Record(feature) = ("The White Album" ~ 1968 ~ "The Beatles")
+ * }}}
+ *
+ * A ``Fields`` also provides the ``mkSchema`` method for creating a
+ * [[org.geoscript.feature.Schema]]. Since a ``Schema`` requires a name and any
+ * geometry fields must specify a [[org.geoscript.projection.Projection]], these
+ * must be passed in to ``mkSchema``.
+ * {{{
+ * val Place = "name".of[String] ~ "loc".of[Geometry]
+ * val schema = Place.mkSchema("places", LatLon)
+ * }}}
+ *
+ * It is possible to create Features instead of modifying them. However, a
+ * Schema is required. The ``factoryForSchema`` method tests a schema for
+ * compatibility with a Fields and produces a feature factory function if the
+ * schema is compatible.
+ *
+ * {{{
+ * val placeSchema: Schema
+ * Place.factoryForSchema(placeSchema) match {
+ * case Some(mkPlace) => mkPlace("Library" ~ Point(1,2))
+ * case None => sys.error("The datastore is not compatible with place features")
+ * }
+ * }}}
+ *
+ * Finally, the ``schemaAndFactory`` method can be used to create a compatible
+ * schema and return it along with the feature factory. It takes the same
+ * inputs as the ``mkSchema`` method.
+ *
+ * {{{
+ * val (schema, mkPlace) = Place.schemaAndFactory("name", LatLon)
+ * }}}
