Version 0.55

This release uses new features from plumed 2.10 to generate the docstrings for the various values in input. These features make the docstrings more meaningful and allow you to distinguish the different types (atoms, scalar, vector, matrix and grid) that are passed between actions. The passing of data is even colour coded so you can more clearly see what PLUMED is doing.

I also changed that code testing is managed. Now a sense check is done on the html that is generated from a plumed input file. In particular I check:

That valid HTML is generated
That all clickable values have a hidden div to appear with the description of the value.
That all shortcuts or switchable inputs generate both the long and short divs containing the inputs.
In other words, I am testing that the various actions that occur when you run the javascript on these actions work.

The other parts of testing are also redesigned so as to ensure that you can change the PLUMED documentation without causing errors in the tests on
