helper to generate filter commands specifying rows of parameters_df that should be altered given combinations of nodes, nodal_types, param_sets, givens and statements
node: string indicating nodes which are to be altered
nodal_type: string. Label for nodal type indicating nodal types for which values are to be altered
param_set: string indicating the name of the set of parameters to be altered
given: string indicates the node on which the parameter to be altered depends
statement: causal query that determines nodal types for which values are to be altered
model: model created with make_model
join_by: string specifying the logical operator joining expanded types when statement contains wildcards. Can take values '&' (logical AND) or '|' (logical OR).
