public mgb::PluginBase (Class PluginBase)
check values of all vars in a graph
This graph should be executed multiple times. On the first execution, all var values would be saved as ground truth. Then each time the graph is executed, the value of a single var would be checked. The var to be checked would start at init_var_idx, and changed to next var in topological order after every var_switch_interval graph executions.
