Beta #5

Changes since v0.4:

• Rename Index.append() to .set()/.setAll().
• Add Plural.replace(elementAtIndex,withNewValue) method.
• Add Plural.copy(Set) method, returning an already-distinct Plural.
• Add Index.setIfAbsent(key,elementSupplier) and .replaceIfPresent(key,elementReplacer)` methods.

Beta #4

Changes since v0.3:

• Changed core Map implementation to LinkedHashMap.

Beta #3

Changes since v0.3:

• Add support for wrapping mutable types in Single to turn them into immutable value types.

Beta #2

Changes since v0.1:

• Added keys() and elements() methods to Index.
• More documentation (but still very much incomplete).
• Single.raw (and therefore SingleString.raw and SingleDecimal.raw) is now protected access level. For SingleString and SingleDecimal, the raw value is still publicly accessible via SingleString.toString() and SingleDecimal.asNumber(), respectively. For the primitive singles, raw remains public access level.
• Removed redundant Pairable interface.
