I noticed that some boolean parameters have missing default values
(enabled/disabled) in the documentation so i checked the initialization
functions to get their default values, also there was some inconsistency
in the representation. During the process , i stumbled upon a typo in
cipso_rbm_struct_valid instead of cipso_rbm_struct_valid.
- Fixed typo in cipso_rbm_struct_valid
- Added missing default value declarations
- Standardized boolean representation (0/1 with enabled/disabled)
