/*
 * Very simple test program to check locator conversion against some other --SF
 * This is mainly to test longlat2locator and locator2longlat functions.
 *
 * Takes at least two arguments, which is a locator and desired locater
 * precision in pairs, e.g. EM19ov is three pairs.  precision is limited
 * to >= 1 or <= 6.  If two locators are given, then the qrb is also
 * calculated.
