Remove scaling from spring example

[francoisdh]

We would like to remove the scaling of the spring example. The unit defined at the first line of docs/modules/centerlines/examples/spring/spring.geo should be 0.1 instead of 10.

This would then allow to remove gmsh.scale=1e-2 option in Feel++ toolboxes spring examples: https://github.com/feelpp/toolbox/blob/master/examples/modules/cfd/examples/spring/spring.cfg

This 100x scaling was introduced as a workaround which should not be required anymore.

Status update:

The last commit is not enough to fix issue #39, angiotk_meshing_remeshstl now seems to hang or run into infinite loop (using 100% cpu) at "run OpenSurface" step.
Last output line:

Info    : AngioTkCenterline: prepare data for cutting done

@francoisdh do you know how to fix that ?

@vincentchabannes any idea ?

[prudhomm]

@francoisdh you should provide some more information and look for yourself also in the code to understand where it gets "stuck"

@prudhomm Ok, I will look it up. I just wanted to post an update about it and ask if there was an already known problem/solution I didn't know about.
