The fundamental infrastructure for all network nodes focusing on non-communication aspects of network nodes.

It provides among others:

• Node(1,2) lifecycle management through NodeStatus
• Optional local clock for modeling clock skew
• Optional modules for with energy storage, management, and generation
• Support for node mobility

NodeBase is not intended to be used directly in simulations but rather serves as a base module for more specialized node types that add communication capabilities.
