What Was Done
Hello, today I implemented the a structural design pattern known as the Bridge Pattern.
I have implemented the bridge pattern in the DATA_SOURCES dictionary. The reason I have done this is because this allows a decoupling between the data source that is provided and the way that the specific implementation of the data source handles returning data.
Specifically speaking, rather than having DATA_SOURCE store a reference of each available data source and then calling a generic method get_all which is implemented in each of those data source objects (NYT, CSBS, JHU) that then superficially just call get_locations; get_locations() is called indirectly by having a 'bridge' method call get_all which then calls get_locations of each data source object.
