/* DOCUMENTATION

This is a rough format converter for pucatrade. Since pucatrade's "import cards"
system is tempremental, I wrote this to deal with it. Note that this was
tailored for my own personal collection, so most sets are not covered (but can
be added below), and that there is no explicit foil-handling or special edition
handling at the present time.

Compiles under C++11

Expected source format:

	1x Shivan Dragon (ORI)
	1x Urborg, Tomb of Yawgmoth (M15)
	1x Chromatic Lantern (RTR)

Intended output format:

	1x Shivan Dragon Magic Origins
	1x Urborg, Tomb of Yawgmoth Magic 2015 Core Set
	1x Chromatic Lantern Return to Ravnica
