    (create-context system)
    Create Context record (map) from system, containing values
    specified by providing calls.
    
    Context record has print-method which hides the real contents.
    (dependencies component)
    Returns the map of other components on which this component depends.
    
    (providing component spec)
    Associates metadata with component describing what values
    the component provides for others to use. Provides are specified
    as a map keys. Keys in the map correspond to key in context map.
    Values in the map are they keys in the component where provieded
    value is. The value can be a IFn so if you need to retrieve
    nested value you can use e.g. `(comp :foo :bar)`.
    Alternatively, if the keys are the same in both the component and
    context, they map be specified as vector of keys.
    (start-system system)(start-system system component-keys)
    Recursively starts components in the system, in dependency order,
    assoc'ing in their dependencies along the way. component-keys is a
    collection of keys (order doesn't matter) in the system specifying
    the components to start, defaults to all keys in the system.
    (stop-system system)(stop-system system component-keys)
    Recursively stops components in the system, in reverse dependency
    order. component-keys is a collection of keys (order doesn't matter)
    in the system specifying the components to stop, defaults to all
    keys in the system.
    (system-map & keyvals)
    Returns a system constructed of key/value pairs. The system has
    default implementations of the Lifecycle 'start' and 'stop' methods
    which recursively start/stop all components in the system.
    
    System maps print as #<SystemMap> to avoid overwhelming the printer
    with large objects. As a consequence, printed system maps cannot be
    'read'. To disable this behavior and print system maps like normal
    records, call
    (remove-method clojure.core/print-method com.stuartsierra.component.SystemMap)
    (system-using system dependency-map)
    Associates dependency metadata with multiple components in the
    system. dependency-map is a map of keys in the system to maps or
    vectors specifying the dependencies of the component at that key in
    the system, as per 'using'.
    (using component dependencies)
    Associates metadata with component describing the other components
    on which it depends. Component dependencies are specified as a map.
    Keys in the map correspond to keys in this component which must be
    provided by its containing system. Values in the map are the keys in
    the system at which those components may be found. Alternatively, if
    the keys are the same in both the component and its enclosing
    system, they may be specified as a vector of keys.
