Should we add a warning when an indexed DFI column is modified ?
This means overriding all the data.frame and matrix replacement operators...

[<-.data.frame
$<-.data.frame
[[<-.data.frame
and the one used by matrix objects

Overriding all the replacement operators for data.frame and matrix is tricky and it will make replacements operations for non-indexed columns slower...
Th DFI objects are supposed to be used as "read-only repository" of indexes, so, in order to avoid the risk to use a DFI object with invalid indexes without warning, we're going to introduce a breaking change and make DFI objects not-inheriting from data.frame or matrix anymore.
