Created empty projekt and modified .gitignore
Added a first a nearly empty layer class and modified .gitignore again
Added propertys "TileAt" and "Title"
They're not 100% ready and untested, but here they are ...
Added dummy decoder for layers
The layer decoder is supposed to be able to decode data from any valid source provided by Tiled. To achieve this, the dummy decoder is prepared to decode gzip, zlib, base64 uncompressed, XML, JSON and CSV.
For a better internal workflow all methods, except of CSV, actually convert the source to CSV and use this one instead.
