Contains classes and interfaces implementing linear referencing on linear geometries

### Linear Referencing

Linear Referencing is a way of defining positions along linear geometries (`LineStrings` and `MultiLineStrings`). It is used extensively in linear network systems. There are numerous possible Linear Referencing Methods which can be used to define positions along linear geometry. This package supports two:

- Linear Location - a linear location is a triple `(component index, segment index, segment fraction)` which precisely specifies a point on a linear geometry. It allows for efficient mapping of the index value to actual coordinate values.
- Length - the natural concept of using the length along the geometry to specify a position.
