Code refactor
>Changed resource class names to be more simplistic and high level
Fixed errors with SDL_Mixer library initialization
Resource Management update
>ResourceManager now creates and loads all current resource types
>Engine now has functions for loading all resource types
Alternative Resource handling structure
>Moved necessary variables out of engine namespace
>Create load and unload functions for Resource base
>Moving Resource specific loading functions into respective resource classes
>Broken Code!<
>Issue involves scope, Engine_Renderer not visible to resource class
even though the class has access to the definition.
>Once error is fixed, resources can now be loaded without the need to cast
Compile error solved, test program now runs successfully.
>Resources loading offloaded to resource classes themselves
	>Allows for better extension of resource management system
>ResourceManager can now be declared singleton and included in engine namespace
Minor update
>Removed unnecessary prints
>Tested resource multiaccess
	>Resource only loaded once
Resources can now only be unloaded when they are loaded
Implemented teardown function for resourcemanager
Mass loading and unloading added to ResourceManager
ResourceManager moved to engine namespace, there is no longer any need
to instantiate a resourcemanager.
Music and TTF resource testing:
>Trouble with WAV files being utilized for music resources.
>mp3 music resources work

Engine class changes:
>Audio channel now opened upon successful initialization of mixer library.
Text management
>Successfully print text to screen
>Text printed to screen properly wraps
>Text resources successfully handled

>Added surface resource
	>Used for handling images that need to be manipulated/edited often
>Resource Branch Finished
>Added mix error line to sfx resource load function
