Is your feature request related to a problem? Please describe.
The sample_app only calls CFE functions; it does not call any OSAL, PSP, or additional library functions like a real app might do.

This makes a difference for Unit Testing. The framework should contain a useful example of UT for apps and libs (related to #21) and the example would be more useful if it called something other than CFE.

Describe the solution you'd like
The sample_app should invoke the SAMPLE_Function as provided in the example sample_lib library.

Describe alternatives you've considered
N/A

Additional context
This change would demonstrate two things:

• demonstrate at runtime that the dynamic linking worked correctly for the libraries (i.e. an app can successfully call into a lib like it is supposed to)
• demonstrate linking to the stubs provided by the library for unit testing
