In this release (ver. 1.2) Python APIs are partially sorted out. Especially baseapi/definition.py and related APIs such as baseapi/definition.py baseapi/definition_extraimplementation.py baseapi/definition_initialvalue.py and convert/definition_extraimplementation_parser.py convert/definition_initialvalue_parser.py convert/definition_parser.py are modified. In this release, definition.py acts as a parental class of definition_extraimplementation.py, definition_implementation.py and definition_initialvalue.py, and definition_parser.py acts as a parental class of definition_extraimplementation_parser.py, definition_implementation_parser.py and definition_initialvalue_parser.py This reformation of APIs might causes errors in scripts written by users based on Python APIs for ver. 1.1.2 and before. Main changes are the following: definition_implementation_*** --> definition_*** definition_initialvalue_*** --> definition_*** definition_extraimplementation_*** --> definition_*** Namely, we changed to let similar functions have the same name. That's it. Only by replacing the name of functions according to above rule, errors must be solved. Previously name of functions were different depending on Classes. For example, DefinitionInitialvalue class has a function set_initialvalue_definition() and DefinitionExtraimplementation class has a function set_extraimplementation_definition(). These classes deal with definition tag in ISML at different location, e.g. in initial-value or extra-implementation, and these classes work in quite similar way. Many of functions can be shared among them. Hence we decided up to rename all functions, and to create a new parental class "Definition" which implements all most all functions managing the definition tag in ISML. And also we added a class DefinitionImplementation which corresponds to Definition class before this reformation. This simplification must be better for users to understand APIs.
