Column names for length results in inconsistent behaviour

[whelena]

In the documentation it says

Multiple length values can be used together. All columns whose names contain length
will be used. (For example, length.1 and snv.length are both valid.)

This is true but I noted some inconsistent behaviour. Not sure if this is intentional, where to activate the automatic features a specific column name needs to be used (lenght.1 and length.2)

Example 1: Lengths specified using length.1 and length.2

Example 2: Lengths specified using snv.length and length.2

Y-axis is not generated for the first specified length (snv.length) and length.2' axis is moved to the left.

Example 3: Lengths specified using snv.length and length.3

Y-axis is not generated for snv.length and length.3 axis is generated to the left. Autp,ated edge colouring does not work, I'm assuming it's not generalized to take in column names other than length.2.

Example 4: Lengths specified using snv.length and pga.length

No y-axis or automated edge.colour.

I think we should restrict column names to length.1 and length.2 for v3 until we can generalize it.

OK, this should work as long as the format is length.<edge name>. The regex won't recognize columns with <edge name>.length.
