Use the same tolerances for comparing text output files as is used for CSV
files. The absolute tolerance is the maximum (less restrictive) of the specified
tolerance and the tolerance implied by the recorded precision.
This corrects the calculation of the least significant digit for all string
representations of for numbers where no decimal point was printed, e.g. "123"
and "45e+06".
The logic for comparing string representations of floats in blessed output files
was incorrect. This caused a number of tests that shouldn't have actually been
passing to indicate success. This error was introduced in r1318.
This will create symlinks (on posix systems) or copies (on Windows)
of the Cantera headers in the 'canterna/kernel' directory,
corresponding to the behavior of older versions of Cantera.
Values are only compared up to the printed precision, so rounding
errors will no longer result in failing tests. This also fixes
differences in floating point output formats on different platforms.
