Allow data modification

[miskovicm]

Hello,

Entries are read-only, which is clearly stated in documentation.

What do you think about marking following \Schematic\Entry variables as protected?

• $data
• $entriesClass

This way I can extend class and update values without generating new object for each update.

Would you even consider this type of change?
Are there any potential drawbacks?

Thanks in advance for your answer.
