FSARunIntegration[path] evaluates a FIESTA script
FiestaScript.m in path. To that aim a
Mathematica kernel is started in the background via
RunProcess. The function returns True if the
evaluation succeeds and False otherwise.
Alternatively, one can use FSARunIntegration[path, topo]
where topo is an FCTopology symbol and the
full path is implied to be
path/topoName/FiestaScript.m.
If you need to process a list of topologies, following syntaxes are
possible FiestaScript.m[{path1,path2, ...}],
FiestaScript.m[path, {topo1, topo2, ...}]
The path to the Mathematica Kernel can be specified via
FSAMathematicaKernelPath. The default value is
Automatic.
