Function addAssertInstFunc

addAssertInstFunc<T>(name: keyof T, func: IScopeFn): void
Adds a single scope function to the assert (instance) prototype, which will extend (or replace) IAssertInst definition, you can then use the IExtendedAssertInst type to cast the instance object returned via the expect function as it will contain the newly added function.

Note: These functions are NOT added to the assert or the instance returned via the createAssert only the IAssertInst object returned via the expect function.
- Use the addAssertFunc or addAssertFuncs to add functions to the IAssertClass and instances returned via createAssert.
