Is there a path from ‘self` to `other` following edges in the dependency graph? @return true iff there is a path following edges within this {#graph}
Creates the initial state for the resolution, based upon the {#requested} dependencies @return [DependencyState] the initial state for the resolution
@return [Conflict] a {Conflict} that reflects the failure to activate
the {#possibility} in conjunction with the current {#state}
Add the current {#possibility} to the dependency graph of the current {#state} @return [void]
@param [String] name @param [Object] payload @param [Array<String>] parent_names @param [Object] requirement the requirement that is requiring the child @return [void]
Detaches the {#vertex_named} ‘name` {Vertex} from the graph, recursively removing any non-root vertices that were orphaned in the process @param [String] name @return [Array<Vertex>] the vertices which have been detached
@param [String] name @return [Vertex,nil] the root vertex with the given name
Removes a possibility from ‘self` @return [PossibilityState] a state with a single possibility,
the possibility that was removed from `self`
Determines whether the given ‘requirement` is satisfied by the given `spec`, in the context of the current `activated` dependency graph.
@param [Object] requirement @param [DependencyGraph] activated the current dependency graph in the
resolution process.
@param [Object] spec @return [Boolean] whether ‘requirement` is satisfied by `spec` in the
context of the current `activated` dependency graph.
