Deletion of Classical Hamiltonian quaternions

Comment: It is clear that quaternions have a long and varied history, and quaternions as they are used today appear to differ in many ways from quaternions as they were used in Hamilton's era. While they are essentially the same mathematical concept, they were originally the precursor to linear algebra and vector calculus. While the classical use of quaternions was largely replaced by linear algebra and vector calculus, quaternions have found new applications in computer graphics and some newer theories of physics. There are a number of independent sources that go into details on the classical quaternions, for example: ''http://books.google.com/books?id=TYaePD53FtQC&pg=PA257 A History of Geometrical Methods'' has a section on "The quaternion calculus of Hamilton", and ''http://books.google.com/books?id=e9wEntQmA0IC&pg=PA191 Oliver Heaviside: The Life, Work, and Times of an Electrical Genius of the Victorian Age'' has a secton on "William Hamilton and Quaternions"; in addition any of the numerous sources about quaternions written in the 19th and early 20th centuries would be appropriate to use for this article. This should be structured as a |summary style spinout from the main quaternion article, but that is an editing issue
