SBDataStructures is a (currently) incomplete set of standard computer data structures implemented in Objective-C. Implementations are often inspired by Robert Sedgewick's Algorithms class on Coursera, and the textbook for that class.
As Objective-C classes, every effort is made to preserve the conventions of Objective-C method names and behavior. Often I look to Foundation or Core Foundation classes for indication of how a method should be named. Consequently, the API will look slightly different from the Sedgewick sources noted above.
