	template<class V> void getFiles(std::string lStrPath, V &lFilesCont)
			- This is a templatized function which expects a directory path and an STL container 
			(vector<string> / list<string>)as a parameter. 
			The function scans the directory for the list of files and stores them in the provided STL contanier.

	void getFilesRecursive(std::string lStrPath, std::list<std::vector<std::string>> &lListFiles)
			- This is a generic global function which expects a directory path and a list<vector<string>> as 
			  a parameter. The function scans each of the sub-directories for the list of files and stores them
			  in a vector<string>. These vector<string> are then added to the list data-structure.
