Generic reaction is a reaction with at least one compound class as reaction participant (e.g., a primary alcohol + NADP -> an aldehyde + H(+) + NADPH). This function checks if given reaction is generic reaction

1	is.generic.rhea(equation,chebi_df,id_col,parent_col,formula_col,direction_type)

`equation`	Reaction equation usually generated by get.rhea.all() function.
`chebi_df`	Chemial table data.frame() containing molecular formula and parent compound
`id_col`	In chemical table, choose the column name which contains chemical id (usually first column)
`parent_col`	In chemical table, choose the column name which contains parent compound ("parent" in chebi)
`formula_col`	In chemical table, choose the column name which contains molecular formula
`direction_type`	In reaction equation, provide reaction direction symbols. Default is c(' <\\?> ', ' <=> ', ' => ')

Logical TRUE/FALSE
