LatLong class

Immutable geographic coordinate representing a point on Earth's surface.

This class stores latitude and longitude values in decimal degrees using the WGS84 coordinate system. It provides conversion utilities for microdegrees (degrees * 10^6) and supports parsing from various string formats.

Key features:

• Immutable design for thread safety
• WGS84 coordinate system compliance
• Microdegree conversion for high-precision storage
• String parsing with multiple separator support
• Efficient equality comparison and hashing

Implemented types

• ILatLong
