Add warning flag for mismatched options?

[amanchoudhri]

If the user supplies inflow files with flag iin=3 but does not update itype to 3, the code fails silently and seems to read from uninitialized memory addresses. This leads to implausibly large inflow values,

 READING INFLOW from /moto/home/ac4972/windopt/simulations/precursor/out/inflow1
 U,V,W max=  2.088587010806605E+294  0.000000000000000E+000

and resulting floating point overflow errors,

A warning message to stdout or stderr might help make debugging more clear to new users (like myself) who don't understand all the configuration options.
