Android Cascaded Data Module

Brief Explanation

The aim is to create an android library capable of enabling 2 features -

1. Nested/Cascaded drop downs
2. Nested search engine in a search box

These features will be backed by a list of cascaded data objects where the data object can be defined as a JSON comprising of n number of keys organised in a linear hierarchy (in a parent-child relationship)

An example of a linear data object could be administrative units (District, Block, Gram Panchayat) where Gram Panchayat unit is a child of parent block and block is a child of parent District.

Features to be Implemented

1. Create a service to download data objects via API
2. Create a manager to modify downloaded data into an optimal data structure efficient for direct and fuzzy search
3. A UI layer able to render data in cascaded dropdowns
4. A UI layer able to render data in a search box capable of providing direct/fuzzy search
