this function look for a field in a structure and give back the structure tree
Branches until the field
inStruct is the name of the structure search
fieldName is the name of the field for which the function searches
input only inStruct and fieldName!!!
it is a recursive function, input of "ind" or "fieldtree" will make a mass
fieldtree is a cell matrix that contain by order the levels of
"fieldName" (return empty matrix if fieldName is not found)
level is the level of fieldName in inStruct structure

example
a.b.c=1;
a.b.d=2;
a.b.f.g=3;
a.h.rrr='lll';
a.t1.t2.t3.t4.t5=true;
a.t1.t2.t3.t4.t6='aaa';
disp('look for ''c''');
[fieldtree, level]=hasfield1 (a, 'c');
disp(fieldtree);
disp(level);
disp('look for ''t5''');
[fieldtree, level]=hasfield1 (a, 't5');
disp(fieldtree);
disp(level);
disp('look for ''t6''');
[fieldtree, level]=hasfield1 (a, 't6');
disp(fieldtree);
disp(level);
disp('look for ''g''');
[fieldtree, level]=hasfield1 (a, 'g');
disp(fieldtree);
disp(level);

results:
look for 'c'
'b' 'c'

2

look for 't5'
't1' 't2' 't3' 't4' 't5'

5

look for 't6'
't1' 't2' 't3' 't4' 't6'

5

look for 'g'
'b' 'f' 'g'
