The samples have become unwieldy when running them from a browser. In particular, the drop-down lists are fixed size with no scrolling, and many of them are now just too large. I have moved all the Calculation samples up a level, and broken several categories (Basic, Chart, DateTime, Engineering, Financial, and Reader) into several pieces. Convert-Online (now found in the Engineering category) had a number of different problems which are now resolved. It is the only member with any significant code change.
