Fix for arrays with user defined lenght
MR proposing a fix for the issue reported in #24 (closed).
FunTuple allows the tupling of arrays with a index variable defined by the user.
The index name is correctly retrieved however it's not removed from the field name used to store the array, leading to an object defined as a matrix.
Removing the index name from the field name allow to store correctly the object in the final tuple.
