Folks will supply a character vector of the kinds of constraints they want to make (e.g., c("loading", "intercept", "residual"), and we will use stringr to detect key words (e.g., loading) to determine what gets constrained at what level
[x] Write new functionality to seek out accepted character options for const_dy_meas and construction_dy_struct (others will only be necessary once longitudinal and group functionality built)
[x] Update argument names for const_dy_meas and construction_dy_struct
[x] Update roxygen documentation (argument names, optionality for character specification, and examples)
Will be a BREAKING CHANGe:
Dyadic constr_dy_meas constr_dy_struct
Time constr_long_meas constr_long_struct
Multi-Group constr_group_meas constr_group_struct
