Replace undefined values on the model grid with valid values at a nearby neighbor.

Undefined values are typically associated with isolated islands where there is no source data. Routine searches a neighborhood with a radius of 100 grid points. If no valid values are found, a default value is used. This routine works for one tile of a cubed sphere grid. It does not consider valid values at adjacent faces. This routine works for fractional categorical fields, such as soil type.

Parameters

[in,out]	field	- input: Field before missing values are replaced. output: Field after missing values are replaced.
[in]	mask	Field bitmap. Field defined where mask=1.
[in]	idim	i dimension of tile.
[in]	jdim	j dimension of tile.
[in]	num_categories	Number of veg/soil categories.
[in]	tile	Tile number.
[in]	field_name	Field name.
