[N-Dekker]

• Addresses issue Let library also print the input parameters to log file #1284

Example "elastix.log" file, with this pull request:

WARNING: The parameter "FixedInternalImagePixelType", requested at entry number 0, does not exist at all.
  The default value "float" is used instead.
  [...]
WARNING: The parameter "Resampler", requested at entry number 0, does not exist at all.
  The default value "DefaultResampler" is used instead.
ELASTIX version: 5.2.0
Command line options from ElastixBase:
-out      B:/data/output/
-priority unspecified, so NORMAL process priority
-threads  unspecified, so all available threads are used
WARNING: The parameter "UseDirectionCosines", requested at entry number 0, does not exist at all.
  The default value "true" is used instead.

WARNING: The option "UseDirectionCosines" was not found in your parameter file.
  From elastix 4.8 it defaults to true!
This may change the behavior of your registrations considerably.

Command line options from TransformBase:
-t0       unspecified, so no initial transform used
