Currently, a seed value is required for foldl which in turn causes aggregate to require a seed value. The functions should be able to be used both with and without a seed value. Additionally, the seed value appears to be misnamed as memo. This should be changed to something more suitable.

Unit tests should be added for these as well. #2 is close to being merged and presumably will have been merged by the time these tests are ready to be built.

Create a chart comparing ShittyLINQ to System.Linq showing whether or not ShittyLINQ has a given method. If a method exists, provide a benchmark for the method in both assemblies showing the performance difference. Describe your methodologies.

These extension methods need unit tests. Should create a unit test project with at least one test for each extension method. Visual Studio Quality Tools Unit Test Framework is preferred.
