Require variable dimensions in argument list?

[cacraigucar]

This issue has bitten me again and probably will be fixed in this repo (and may get lost in the NCAR repo issues) which is why I'm duplicating it here. I was doing code cleanup, and removed a dimension which was in the calling list of a routine, but not being used in it internally. It turns out that this variable was the one I put in to workaround this issue.

The standard name of the variable in question is "variable_layer_dimension". This is assigned a value in the host model and resides as a host level module data field and is known as nlayer. When I have a array which does not exist at the host model level, but only at the scheme level the allocate for the array inside ccpp_MusicBox_suite_cap.F90 says
allocate(dto2(1:nlayer,1:tuv_n_wavelen)). The error is that "symbol nlayer has no IMPLICIT type"
