name		The map projection used in WKT format, or as "epsg:xxxx" or "esri:xxxx".	required
xstep	float	The number of units horizontal distance a step of one pixel makes in the map projection.	required
ystep	float	The number of units vertical distance a step of one pixel makes in the map projection.	required

Examples:

Create a map projection using an EPSG code:

>>> proj_wgs84 = MapProjection("epsg:4326", 0.001, -0.001)

Create a projection using an ESRI code:

>>> proj_esri = MapProjection("esri:54030", 1000, -1000)
