'read_ncvar': reads a list of fields and constants in a netcdf file
------------------------------------------------------------------
[cte_detect,var_detect,cte_read,var_read,choice,cte2_detect,var2_detect,cte2_read,var2_read]=...
read_netcdf(filename,cte1,nb1,var1,cte2,nb2,var2,option)
OUTPUT:
cte_detect: array with the dimension of cte1 or cte2 (option 'or'), =1 if the constant is detected 0 else.
var_detect: like cte_detect for the variables
cte_read: list of the values for the constants (global attributes), =0 if not detected
var_read(ind,:): variable array number ind, the variable #i is determined as var_read(ind(i),:), with ind=cumsum(var_detect);
choice=1 if the first list is chosen (or with the option 'and'), 2 else.
cte2_detect,var2_detect, cte2_read,var2_read, second set of v ctes and variables (only with the option 'and')
INPUT:
filename (netcdf file)
cte1: cell array listing the constants (global attributes) to read
nb1: name the constant in the netcdf file giving the length of var1 (if absent no variable is read)
if nb1 is a cell array, nb1{i} corresponds to the choice by order of priority (as given by varname_generator)
and cte{i,:} is the corresponding list of constants
var1{i,:}: list of variables arrays to read by order of priority with length nb1{i}
cte2,nb2,var2: second list of cte and variables (optional)
