The framework manager is the main class through which user code will interact with the Mantid framework. It is the center piece of the application programming interface.
The main purpose of the frameworkManager is to simplfy the interaction with the various internal services of the Mantid framework. Of course this does not prevent you from accessing those services directly should you so wish.
The frameworkManager allows you to create and execute algorithms as well as retrieving workspaces, and deleteing them if they are no longer required.
It is good practice to delete workspaces that are no longer required to free up the memory used.
For the most up to date listing of the methods that Framework Manager provides look at the Doxygen code documentation. Select the classes tab and look for FrameworkManagerImpl (Mantid::API).
