TextFile model fails silently with incompatible calibration data

[IvanHeriver]

Description

For certain formula, certain input values are not permitted. For example in the equation h^c where h is the input variable, if the calibration data contains a negative input value (and c is not an integer) the equation is no longer valid. However, BaM produces results when I think it should fail with an explicit error message. Instead Results_MCMC_Cooked.txt contains the same value repeated for each row and LogPost values are set to NaN.

This is not so problematic since the results are clearly not valid but I'd prefere BaM to crash.

Reproduction

In the attached file, you can test this by modifying the calibration data (file Data_fakeCalibrationData.txt) from the not working case

X_h Y_Q
-1.0 0.0

to this working case

X_h Y_Q
1.0 0.0

Not that for this example to work, you need to launch BaM from within the directory where all the config files are since relative paths are broken otherwise (I might open another issue for this). From within the config files directory, run /path/to/BaM/exe -cf "./Config_BaM.txt
