1%'find_field_cells': analyse the field structure for input in uvmat functions, grouping the variables  into 'fields' with common coordinates

5% OUTPUT:
6% CellInfo: cell of structures describing field cells
7%     .CoordType:  type of coordinates for each field cell = 'scattered','grid','tps';
8%     .CoordIndex: array of the indices of the variables representing the coordinates (in the order z,y,x)
9%     .CoordSize: array of the nbre of values for each  coordinate in a grid, nbre of points in the unstructured case
10%     .NbCentres_tps:
11%     .SubRange_tps
12%     .VarIndex: arrays of the variable indices in the field cell
13%     .VarIndex_ancillary: indices of ancillary variables
14%              _color : color image, the last index, which is not a coordinate variable, represent the 3 color components rgb
15%              _discrete: like scalar, but set of data points without continuity, represented as dots in a usual plot, instead of continuous lines otherwise
16%              _errorflag: index of error flag
17%              _image   : B/W image, (behaves like scalar)
18%              _vector_x,_y,_z: indices of variables giving the vector components x, y, z
19%              _warnflag: index of warnflag   
20%       .DimIndex
21%      .ProjModeRequest= 'interp_lin', 'interp_tps' indicate whether lin interpolation  or derivatives (tps) is needed to calculate the requested field
22%      .FieldName = operation to be performed to finalise the field cell after projection
23%      .SubCheck=0 /1 indicate that the field must be substracted (second  entry in uvmat)
24% NbDim: array with the length of CellVarIndex, giving the space dimension of each field cell
25% errormsg: error message
26%   
27% INPUT:
28% Data: structure representing fields, output of check_field_structure
29%            .ListGlobalAttributes
30%            .ListVarName: cell array listing the names (cahr strings) of the variables
31%            .VarDimName: cell array of cells containing the set of dimension names for each variable of .ListVarName
32%            .VarAttribute: cell array of structures containing the variable attributes:
33%                     .VarAttribute{ilist}.key=value, where ilist is the variable
34%                     index, key is the name of the attribute, value its value (char string or number)
35%            .Attr1, .Attr2....
36%        case of actual data:
37%            .Var1, .Var2...
38%        case of data structure, without the  data themselves
39%            .LisDimName: list of dimension names
40%            .DimValue: list of corresponding dimension values
41% HELP:
42% to get the dimensions of arrays common to the field #icell
43%         VarIndex=CellVarIndex{icell}; % list of variable indices
44%         DimIndex=Data.VarDimIndex{VarIndex(1)} % list of dimensions for each variable in the cell #icell
