This implements the main unsubdivide algorithm which rebuilds a base mesh and extracts the grid's data from a high resolution mesh. It includes the Rebuild Subdivisions operator, which generates all subdivision levels down to the level 0 base mesh. It supports: - Rebuilding an arbitrary number of levels (Unsubdivide) or as many levels as possible down to level 0 in a single step (Rebuild Subdivisions). - Rebuilding with already existing grids. - Meshes with n-gons and triangles - Meshes with more than 2 faces per edge - Base mesh made completely out of triangles - Meshes without poles - Meshes with multiple disconnected elements at the same subdivision level Reviewed By: sergey Differential Revision: https://developer.blender.org/D7372
