Thank you for submitting a pull request to the CABLE Project.

Description

The retrieving of dimension IDs from input NetCDF files is inconsistent across the code. Add routines to the cable_common module to standardise the retrieving of said IDs by searching through a list of possible names for the dimension.

Made some adjustments- now a single routine, with the possible names defined in the cable_common module. Used the NF90_BADDIM as the default for ok, since I'm fairly sure that's what the routine throws when the dimension can't be found.

I've changed to square brackets and made the lists of names PARAMETERs.
