Fix output of initial temperature
Merge branch 'base'
Improved HDF5 output.

* Add limits, ranges, names of files.
* Remove use of herr_t status variable, since it isn't being checked
  anyways.
Remove use of herr_t status variable, as it wasn't being checked.
Merge branch 'base'
HDF5 write changes, set sigma multiplier in initial position.

* Rename the upper/lower limits and range values to
  param_lowlim, etc. to avoid conflict with all parameter level
  has_lower_limit, etc.
* Set the last and last two parameters in initStep to be 1.0 for
  the sigma multiplier.  Previously, they weren't initialized
  (which didn't affect any fits, but does affect the HDF5 output).
