Re-implementation of DictionaryArray

[tapy-lappy]

Need to investigate following:

• [ ] Implementation of [key: number | string]: T; - and when it will be implemented - no dictionary/array/lenght are needed anymore - we actually have already had index access by this.storage[index] no matter what index is either number or string. It would be much more convinient to have indexed access to dictionar/array then 2 access props:

  get dictionary(): Dictionary<T>{return this.toDictionary();}
  get array(): Array<T>{return this.toArray();}

  which we use into GeneStorage. So it's also need refactoring;

• [ ] we may eliminate interface IDictionary at all;
• [ ] also we have to much type aliaces. We may shortage their amount:

  export type KeyValuePair<T> = {keyIndex: number|string, value: T};
  export type Predicate<T> = (item:T)=>boolean;
  export type Selector<T> = (item:T)=>string;
  type KeyValuePairTransformer<T> = (item:T)=>KeyValuePair<T>;
  export type ArrayMapper<T> = {mapper: KeyValuePairTransformer<T>};
  export type ArrayConverter<T> = Array<T> & ArrayMapper<T>;
