!  1. Purpose :
!
!     Manages user configurable netCDF meta-data for ww3_ounf program.
!
!  2. Method :
!
!     Default netCDF meta data is provided for each WW3 output variable
!     and is stored intentally via the META_T type. The meta values are
!     grouped by component (max 3), field (IFI) and group (IFJ).
!
!     The user can override this meta data via an input text file
!     with the filename `ounfmeta.inp`.
!
!     Entries in the file are formatted as follows:
!
!       META [ IFI [ IFJ ]  |  FLDID ]   [ IFC ]
!         attr_name = attr_value
!         attr_name = attr_value
!         extra_attr = extra_value [type]
!       ... repeated as many times as required.
!
!     An output field is selected using the META keyword followed by
!     either an [IFI, IFJ] integer pair or a FieldID string. Optionally,
!     either form may be followed by an integer value to select the
!     component in multi-component fields (such as wind).
!
!     Blank lines and comments lines (starting with $) are ignored.
!
!     attr_name is the netCDF attribute name that you wish to override.
!     This can be one of the following:
!         -  "varnm"
!         -  "ename"
!         -  "standard_name", or "varns"
!         -  "long_name" or "varnl"
!         -  "globwave_name" or "varng"
!         -  "direction_reference", "dir_ref" or "varnd"
!         -  "comment" or "varnc"
!         -  "units"
!         -  "valid_min" or "vmin"
!         -  "valid_max" or "vmax"
!         -  "scale_factor" or "fsc"
!
!     Any other attribute name is assumed to be an optional "extra"
!     attribute. This extra attribute can take an optional "type"
!     keyworkd to specify the variable tpye of the metadata. If
!     no type is supplied, it defaults to a characer type. Valid
!     types are one of ["c", "r", "i"] for character/string,
!     real/float or integer values respectively.
!
!     Global meta data can be specified with a special "META global" line:
!
!       META global
!         extra_attr = extra_value [type]
!         extra_attr = extra_value [type]
!
!     A "coordinate reference system" (CRS) can be specified for all output
!     fields using the "CRS" keyword. As a minimum, the "grid_mapping_name"
!     attribute must be specified. If the CRS section is defined, all output
!     fields will have a "grid_mapping" attribute added referencing the
!     CRS variable. "crs_vaname" will be created as a scalar NF90_CHAR
!     variable in the output file.
!
!       CRS <crs_varname>
!         grid_mapping_name = <mapping name>
!         attr = value
!         attr = value
!
!     Note: ALL keywords and "Field Name ID" strings (e.g. HS) are
!     case insensitive. All netCDF attribute names are case sensitive.
!
!     Partitioned outputs are handles slightly differently; one meta data
!     entry is used for all partitions of a field. The metadata is made
!     specific to a particular partition via template strings. There are
!     two built-in template strings: SPART and IPART. These provide a
!     "string" description (e.g. "wind sea", "primary swell", etc) or an
!     integer partition number. These can be references in the meta data
!     using the template name surrounded by < .. >, e.g. <SPART>
!     
!     It is also possible to supply user defined partitioned parameter
!     template strings in the ounfmeta.inp file using the TEMPLATE
!     keyword, as below:
!
!       TEMPLATE <template-name>
!         String for partition 0
!         String for partition 1
!         String for partition 2
!         String for partition 3
!         ... etc
!
!     Specifying the <template-name> with a trailing underscore will
!     provide an underscore seperated (_) string, rather than space
!     seperated.
!
!
!     Example ounfmeta.inp file:
!     ==========================
!
!        $ Lines starting with dollars are comments.
!        $ The line starts a meta-data section for the depth field
!        META DPT
!          standard_name = depth
!          long_name = "can be quoted string"
!          comment = or an unquoted string
!          vmax = 999.9
!
!        $ Next one is HSig (group 2, field 1)
!        META 2 1
!          varns = "sig. wave height"
!          varnl = "this is long name"
!
!        $ Next one is second component of wind. It also sets an
!        $ "extra" meta data value (height - a float)
!        META WND 2
!          standard_name = "v-wind"
!          height = 10.0 "r"
!
!        $ User defined partitioned parameters template strings:
!        TEMPLATE PARTSTR
!          wind wave
!          primary swell
!          secondary swell
!
!        $ Use partition templates in partitioned Hs field:
!        $ (SPART and IPART are built-in)
!        META PHS
!          standard_name = "<SPART_>_sigificant_wave_height"
!          long_name = "<PARTSTR>"
!          partition_number = "<IPART>"
!        
!        $ Coordinate reference system:
!        CRS crs
!          grid_mapping_name = "latitude_longitude"
!          semi_major_axis = 6371000.0 f
!          inverse_flattening = 0 f
!
!        $ Global metadata:
!        META global
!          institution = UKMO
!          comment "space seperated strings should be quoted" c
!          version = 1.0 r

!
!  1. Purpose :

!     Both forms can also specify an optional component (IFC) integer
!     value for multi-component fields (defaults to 1).

!     Field name ID tags are case-insensitive, HS == hs == Hs.

!
!  1. Purpose :
!
!     Reads in attribute name/value pairs and updates the relevant

!     Keeps looping over input lines in file until next META section
!     or EOF is found. Splits meta pairs on the = character.
!
!     Note - the "extra" metadata pair can also provide a variable
!     type ("c", "i", or "r"; for character, int or real respectively)
!
!  3. Parameters :
