Measure along features (Trace measurement)

[LyonMNGIS]

Please consider adding the ability to measure along features similar to how we can trace features when we edit them.  This is different than the current measure features as measure features will measure the entire feature, where "Trace Measurement" will measure a portion of a feature as needed by the user. 

Example use: 

Measuring complex features is often difficult if not impossible if the we are measuring only a part of a feature such as the distance of a stream between two bridges.  The only workaround is to split the river and use the measure feature tool.

Thank You
