LatLon2XY.centered

computes the centered coordinate transformation from lat/lon to map tile coordinates

The function LatLon2XY.centered(MyMap, lat,lon,zoom) computes the coordinate transformation from lat/lon to map tile coordinates given a map object.

LatLon2XY.centered(MyMap, lat, lon, zoom)

`MyMap`	map object
`lat`	latitude values to transform
`lon`	longitude values to transform
`zoom`	optional zoom level. If missing, taken from `MyMap`

properly scaled and centered (with respect to the center of MyMap ) coordinates

`newX`	transformed longitude
`newY`	transformed latitude
