[Gmsh] Error codes.

[Max Orok]

I tried to make a rough taxonomy a while back.
The same error code might mean something different depending on the
function
(function returning 1 in gmsh::option namespace means something different
than for gmsh::model namespace)


*Gmsh error codes: *
*Error code -1 (everywhere):*
The Gmsh context wasn't properly initialized, or a required library
component is missing.
For example, calling any `fltk` functions without a linked FLTK library.

*gmsh*/

*Error code 1*
One of Gmsh's "shell" methods couldn't run successfully.
For example, a bad file path was given to the `open` function.


*gmsh/model, gmsh/view, etc. *
*Error code 1*
A function that mutates the model couldn't complete successfully.
For example, addPoint couldn't succeed because of a tag collision.

*Error code 2*
A model lookup function failed.
For example, tried to call a function on a view that doesn't exist.


*Error code 3 (rare) *
The function couldn't successfully use a required input parameter.
For example,  a user-specified quadrature scheme couldn't be applied to the
data.

*Error code 4 (rare)*
A parallelizable mesh query function failed

*gmsh/option*
*Error code 1*
The given option doesn't exist in Gmsh.

There's some functions that don't fit. I think error code 2 in particular
is a bit of a catch-all.
