%'set_field_list': defines variables needed for the diff fields(velocity, vort, div...) 
%---------------------------------------------------------------------
% [FieldList,VecColorList]=set_field_list(UName,VName,CName)
%
% OUTPUT:
%  FieldList: list (cell column) of the fields to propose in the menu FieldName
%  VecColorList: list (cell column) of the fields to propose in the menu for vector color
%
% INPUT:
%  UName: name of the x vector component
%  VName: name of the y vector component
%  CName: name of an additional scalar for color
%
% RELATED FUNCTIONS:
%  varname_generator.m: determines the field names to read in the netcdf
%  file, depending on the scalar
