Unknown mmp subkey: $AREA

[MuellerSeb]

While checking the actively ran Benchmarks, I found an unknown Sub-keyword ($AREA) in the following two mmp files:

T/HT_var_density_1D.mmp
T/Viscosity/viscosity_yaws.mmp

Should it be $GEOMETRY_AREA?

@MuellerSeb You are right. For these two benchmarks, the variable corresponding to $GEOMETRY_AREA takes the default value of 1.0 because that the wrong keyword is skipped in the reading.

Thanks for the findings. Would you please send a PR for this?
