%'fullfile_uvmat': creates a file name from a root name and indices. 
%------------------------------------------------------------------------
% filename=fullfile_uvmat(RootPath,SubDir,RootFile,FileExt,NomType,i1,i2,j1,j2)
%------------------------------------------------------------------------           
% In the absence of input argument this function tests itself on a set of
% examples
%------------------------------------------------------------------------
% OUTPUT:
% filename: string representing the full file name (including path)
%------------------------------------------------------------------------
% INPUT:
%RootPath: path to the base file
%SubDir: name of the SubDirectory for netcdf files (relevant for NomTypes with index pairs 1-2 or ab )
%RootFile: FileName without appendix
%FileExt: file extension
%NomType: char chain characterizing the file nomenclature, made as
%   nom_type='': constant name [filebase ext] (default output if 'nom_type' is undefined)
%   nom_type='*':constant name for a file representing a series (e.g. avi movie)
%   nom_type='1','01',or '001'...': series of files with a single index i without separator(e.g. 'aa045.png').
%   nom_type='_1','_01','_001'...':  series of files with a single index i with separator '_'(e.g. 'aa_045.png').
%   nom_type='1a','1A','01a','01A',... with a numerical index and an index letter(e.g.'aa45b.png') (lower or upper case)
%   nom_type='_1a','_1A','_01a','_01A',...: idem, with a separator '_' before the index
%   nom_type='_1_1','_01_1',...: matrix of files with two indices i and j separated by '_'(e.g. 'aa_45_2.png')
%   nom_type='_1-2': from pairs from a single index (e.g. 'aa_45-47.nc')
%   nom_type='_1_1-2': pairs of j indices (e.g. 'aa_45_2-3.nc')
%   nom_type='_1-2_1': pairs of i indices (e.g. 'aa_45-46_2.nc')
%   nom_type='_1_ab','1_ab','01_ab'..., from pairs of '#' images
%   (e.g.'aa045bc.nc'), ext='.nc'
%i1: first number i
%i2: second number i (only for .nc files)
%j1: first number j
%j2: second number j (only for .nc files)
