Please describe what your PR is adding in terms of features or bugfixes:

This PR proposes to use an established auto formatter for C code, and then applying said formatter in components.

This is of course only possible by treating each different section (TRACE SHARE etc.) as its own little C code.

I propose this in order to improve the readability of the larger components after multiple people with different editors have changed indenting and therefore arrive at inconsistent indenting.

Examples of the microsoft formatter applied to code is in this pull request the Monochromator_bent.comp, Monochromator_bent_complex.comp and Union_mesh.comp.
