The 🆕 normal

Added support for item normalization.

Updated

• README is broken down into smaller sections.

Added

• Added TallyNormalizer protocol for items to describe how they should be normalized.
• Added normalized closure to Tally model so that models can define on a case-by-case situation how items should be normalized.

Persistence is futile 🔑

This release is all about enabling Tally models to have a custom stores, which in turn allows for features like persistence!

Updated

• n-grams are represented by an array of NgramElement instead of Node.
• Tally is updated so that the representation of the model is moved into a separate TallyStoreType object.

Added

• TallyStoreType, the protocol defining implementation of a Tally store.
• TallyStoreTreeNode, a protocol for the recommended approach of implementing TallyStoreType, but creating a tree-based store.
• MemoryTallyStore, a tree-based in-memory store used by default for models. Available for use for any Hashable items.
• CoreDataTallyStore, a tree-based store backed in turn by a Core Data store. Available for use for any LosslessConvertible items.
• LosslessConvertible, a protocol which when implemented allows a type to convert between itself, and a representation that can be stored within the CoreDataTallyStore object model.
• Simple example of iOS app using Tally to implement a predictive text view for a text field.
• New logo!

Fixed

• Access level errors so that Tally can be used when imported as a framework.
