[!352] add ctype dependent tolerance to grid tests

Merge branch 'issue/test_tolerances' into 'master'


### Summary

Change the fixed hard coded tolerances in grid tests with something related to

### Details

Many tolerances in the grid tests are hard coded to something like 1.e-8.
Those tests will fail if ctype=float. Thus, all those comparisons are changed
to either sqrt(numeric_limits<ctype>::epsilon()) or
numeric_limits<ctype>::epsilon(), depending on the previous value.

### Discussion

The tolerance values seem quite arbitrary. Sometimes it is compared against
1.e-8, sometimes 1.e-7 or 1.e-6 or 1e3*numeric_limits<ctype>::epsilon(). Maybe
it would be cleaner to use the FloatCmp utilities and clearly define what's
the expected accuracy.
