Word "edge" conflicts with pre-defined keyword in DOT Language

[IshaanDesai]

If user uses the word "edge" as a name in the preCICE configuration XML file then running the config-visualizer produces the following error:

Error: <stdin>: syntax error in line 31 near 'Edge'

This is because "edge" is a standard keyword in DOT Language. This case was encountered when configuring preCICE for a plasma physics application where one participant refers to the "edge" region of a fusion reactor.

This is a very edge case and the purpose of this issue is to document this very edge case.
