public final class Sets extends Object
This class should be used to create instances of MutableSet, ImmutableSet and FixedSizeSet

Mutable Examples:

 MutableSet<String> emptySet = Sets.mutable.empty();
 MutableSet<String> setWith = Sets.mutable.with("a", "b", "c");
 MutableSet<String> setOf = Sets.mutable.of("a", "b", "c");
Immutable Examples:
 ImmutableSet<String> emptySet = Sets.immutable.empty();
 ImmutableSet<String> setWith = Sets.immutable.with("a", "b", "c");
 ImmutableSet<String> setOf = Sets.immutable.of("a", "b", "c");
FixedSize Examples:
 FixedSizeSet<String> emptySet = Sets.fixedSize.empty();
 FixedSizeSet<String> setWith = Sets.fixedSize.with("a", "b", "c");
 FixedSizeSet<String> setOf = Sets.fixedSize.of("a", "b", "c");
MultiReader Examples:
 MultiReaderSet<String> emptySet = Sets.multiReader.empty();
 MultiReaderSet<String> setWith = Sets.multiReader.with("a", "b", "c");
 MultiReaderSet<String> setOf = Sets.multiReader.of("a", "b", "c");
