Guidlines for adding a new parameter

[NicWayand]

Looking for guidance on adding a new parameter. I have followed some of the previous PR steps, but still getting index errors, which I suspect means I missed a step. I didn't see any documentation on this so started this thread. Thank you in advance for your help!

I am trying to add a new parameter to summa_zLocalParamInfo.txt

To do this I have modified the following files:

• summa_zLocalParamInfo.txt
  (1) Added the new parameter
• get_ixname.f90
  (1) (code) Add new line within get_ixparam()
• popMetadat.f90
  (1) (code) Add new line in "local parameter data" section (mpar_meta)
• var_lookup.f90
  (1) (code)Add new line in define model parameters
  (2) (code) Add a new index under "named variables: model parameters" for iLookPARAM. If last value was 159, add 160.

Current error is below. This is a 1 HRU test run that is successful without these changes.

Ok please disregard the above error, it does not have anything to do with the above changes. Even on the current develop branch, I get that error only when the the "Debug runs" compiler flags (gfortran) are turned on, but no errors when using "Production runs". Maybe related to some modifications of a new vegetation type I made.
