Part 1 (26.01.2007)
In its current form, these are lecture notes and not a book. There are almost no references given, and also the introduction will be rewritten. The second author just taught the contents of Part 1 to 2nd/3rd year undergraduates. It took 26 lectures, 90 minutes each, to cover the material.
Part 2 should be available in July 2007.
