- added backwards calculation of hkl from four circle angles. This

required inclusion of a matrix package.
- modified  counter error handling to send a Stop when the _BAD_BUSY
  error is received.
- added an environment interface to the general controller stuff in choco.*
  Also added setting a parameter directly at the controller object.
- Added a driver for the ETH High Temperature Furnace to be used at
  SANS.
