Peridynamic Master Action System
Description
The peridynamics mechanics Action is a convenience object that simplifies part of the mechanics system setup. It sets up force density integral Kernels for all displacements at once.

Example Input Syntax
Subblocks
The subblocks of the Mechanics action are what triggers MOOSE objects to be built. If none of the mechanics is subdomain restricted a single subblock will be used.
