## Description

LayoutManagerGroup is a library of custom layout managers for Android RecyclerViews. It serves as a custom list layout engine and a set of UI components designed to control how items are positioned and scrolled within a mobile interface.

The project provides a mechanism for defining non-standard item placements and scrolling behaviors. It allows for the creation of specialized grid and list arrangements that deviate from standard layouts to achieve specific visual configurations.

The engine handles the spatial positioning of items through coordinate-based placement and orientation-aware logic. It manages the rendering process via manual measurement passes and dynamic view recycling to synchronize item positions with scroll offsets.
