### Polish format input file format

This is the input file reader for the Polish format. This is the input format for cGPSmapper and is also by several other map editing tools.

As the polish format is designed for representing Garmin maps, it is very easy to read it into mkgmap, in fact I was a bit suprised how it all just worked.

Having said that, this is just a basic implementation and many of the command tags in the format are just ignored.

It is a good starting point for someone that is wanting to write a new input file plugin for mkgmap as there are no complicating requirements.
