finally some updates.
> added exception class. still minimally implemented
> added main class CareerGuidance that will be the singleton class. It contains all access to the objects and datasources
> implemented some functions required for the datasource and model integration. Still work in progress
> added test_db activity and another annoying button. Please keep it somewhere invisible for my testing of the functions.
> see function list file for implemented functions. But might be easier to just see implemented functions in careerGuidance object
