/**
 * Class Mercator1SP defines the Mercator method with one standard parallel.
 *
 * The 'source' CRS is the geographic CRS.
 * The 'target' CRS is the projected CRS.
 *
 * Based on the following document:
 *
 * Coordinate Conversions and Transformations including Formulas
 * Guidance Note Number 7, part 2
 * Revised January 2009
 * Available at: http://www.epsg.org/
 *
 * Formulas: see 1.3.3.1 -> 1.3.3.2
 *
 * Note that in these formulas common to both 1SP and 2SP cases, the parameter latitude of natural origin (latN)
 * is not used. However for the Merctor (1SP) method the EPSG dataset includes this parameter, which must
 * have a value of zero, for completeness in CRS labelling.
