#6 Multiple Data Point

[Matt Paulin]

With the current design a user can create two differen data point codes but, they will be written to the
same table. This needs to be fixed.

1) The data points need to be unique
2) They can't be type save because you can't necessarly cast them back to the correct type when
reloading them from the data base

Perhaps the type could be saved as a string in the class?
