%% PRIORITY HANDLING AND PRIORITY CALCULATION
%%
%% Handling of ready nodes and priorities.
%% - at present, all nodes have the same priority and so on.
%%
%% *** UNFINISHED ***
%% - should compute a static priority estimate
%% - should dynamically modify priorities + possibly insert NOPs
%% (e.g., to separate branches, etc.)
%% - thus, ought to be passed the current schedule and/or resources as well
