6% This function detects the existence the constructed file name and it can
7% find indices according to file existence if they are not specified
8% rmq: this function is related to the reverse functions display2name and name2diplay
9%------------------------------------------------------------------------
10% OUTPUT:
11% filename: string representing the file name (including path)
12% num_i1_out,num_j1_out,num_i2_out,num_j2_out,subdir_out: index numbers and subdirectory detected
13%            for free input (= to the corresponding input indices when comp_input=1)

15% INPUT:
16% 'filebase': the root name,

21%   nom_type='': constant name [filebase ext] (default output if 'nom_type' is undefined)
22%   nom_type='*':constant name for a file representing a series (e.g. avi movie)
23%   nom_type='1','01',or '001'...': series of files with a single index i without separator(e.g. 'aa045.png').
24%   nom_type='_1','_01','_001'...':  series of files with a single index i with separator '_'(e.g. 'aa_045.png').
25%   nom_type='1a','1A','01a','01A',... with a numerical index and an index letter(e.g.'aa45b.png') (lower or upper case)
26%   nom_type='_1a','_1A','_01a','_01A',...: idem, with a separator '_' before the index
27%   nom_type='_1_1','_01_1',...: matrix of files with two indices i and j separated by '_'(e.g. 'aa_45_2.png')
28%   nom_type='_i1-i2': from pairs from a single index (e.g. 'aa_45-47.nc')
29%   nom_type='_i_j1-j2': pairs of j indices (e.g. 'aa_45_2-3.nc')
30%   nom_type='_i1-i2_j': pairs of i indices (e.g. 'aa_45-46_2.nc')

33%       comp_input=1: the index pair is imposed,
34%       comp_input=0: the index pair is automatically searched, choosing the most recent  file in case of multiple choice
35% 'num_i2': second index i (for nom_type involving index pairs (e.g. netc))
36% 'num_j2': second index j (for nom_type involving index pairs (e.g. netc))
37% 'subdir': (used for nom_type=netc...) string representing the name of the subdirectory 'subdir' containing file.
38%       subdir='': no subdirectory,
39%       subdir='?', the file is first searched with no subdirectory, then in the most recently modified subdirectory if not detected.
