Detailed Description

NodeCommMgr (Node communication manager) is responsible for keeping track of nodes that require communication (shared nodes).

All shared nodes are put into this class through the addSharedNodes function. When they've all been put in, initComplete() is called, which allocates a list of pointer-to-NodeDescriptors.

Before initComplete is called, all nodes that appear in local element- connectivities should be passed to NodeCommMgr using the informLocal function.

The communication that must then happen is this:

For all nodes that we own, we must send their field-IDs and (global) equation numbers to the remote processors that share the node.

For all nodes that we don't own, we need to receive the field-IDs and equation numbers.
