Support for exporting data to schematic files

[ryandev2]

See #3

This is an unfinished PR, the abstract SchematicBuilder is basically finished but the individual format builder implementations are yet to be done.
I would like to know if you like this implementation @SandroHc.

Looks really good so far. I suggest you keep the exporters for a later date, as creating an exporter for each format will be a monumental task and it doesn't seem to be required for #3.
