Over-writing of meshVariable.sym

[lmoresi]

The meshVariable.sym value should be read only.

I don't think there is any reason to change this once the variable has been defined. If there is, it should not be easy to do it unintentionally.

@julesghub - can you look at this ? The meshVariable is using a property with no setter, so I don't understand why this is over-written. Shouldn't it throw an error ?
