Add empty output & scratch dirs to ismip-hom test
Merge branch 'bugfix/v2.0.2'
Merge branch 'master' into develop

Getting v2.0.2 onto develop
Remove DNO_RESCALE from scripts where not needed; also updated a few "GLIMMER_*" build script vars to "CISM_*"
Merge branch 'bugfix/v2.0.3'

Removed DNO_RESCALE line from CISM-only build scripts; replaced some GLIMMER_ prefixes in build scripts with CISM_
Merge branch 'master' into develop
Fixed two bugs in subroutine glissade_calcbmlt

(1) Sometimes bflx was computed to be very slightly difference from zero, resulting
    in a very slightly negative value of bmlt, which triggers an erroneous drop of 0.01 deg
    in the temperature at the bed.  With the fix, bflux is set to zero if the computed
    magnitude is less than 1.d-11 W/m^2.

(2) The call to glissade_calcpmpt had incorrect vertical indexing, resulting in incorrect
    values for the pressure melting point temperature in the column.  The indexing is now correct.

Both bug fixes are answer-changing in problems with an evolving temperature field,
including EISMINT-2.
Added 'parameter' to the declaration of eps11 in glissade_calcbmlt.
Merge bugfix/v2.0.4: bmlt fixes

* piscees/bugfix/v2.0.4:
  Added 'parameter' to the declaration of eps11 in glissade_calcbmlt.
  Fixed two bugs in subroutine glissade_calcbmlt
Merge 'master' into develop: get v2.0.4

Bring in the following changes from master to develop:
* master:
  Added 'parameter' to the declaration of eps11 in glissade_calcbmlt.
  Fixed two bugs in subroutine glissade_calcbmlt
fix typos, make more informative error message
Merge sacks/check_beta into develop

This branch generates an error when which_ho_babc = 5 but
no beta field was input.

* piscees/sacks/check_beta:
  fix typos, make more informative error message
  change error message
  initialize beta to an unphysical value, and add a check to ensure that beta has been read from file correctly if using HO_BABC_EXTERNAL_BETA
