Space in Model name leads to compilation error

Hi, just a small bug I encountered: Trying to solve a model whose name contains a space leads to a compilation error, but there is no clear indication that the name is invalid. Also, it should not be possible to assign an invalid name in the first place.

A small example:

from gamspy import Container, Model, Sum, Sense

c = Container()
a = c.addSet("a", records=["a"])
var = c.addVariable("v", domain=a)
eq = c.addEquation("eq", domain=a)
eq[a] = var[a] >= 1

m = Model(container=c,
          name="with space",
          problem="LP",
          equations=c.getEquations(),
          sense=Sense.MIN,
          objective=Sum(a, var[a]))

m.solve()

This leads to the following error:

GamspyException:

Meaning of return code 2: There was a compilation error
