Profile the time to read the xml file and to generate the wrapper #11

We can imagine to cache this process:

using Pickle
or generate a Python module
generate a wrapper for each versions/profiles at installation, since it is tractable
or on the fly as a .pyc

basic-wrapper-test shows clearly the wrapper generation takes some times.

After measuring the time of each initialisation steps, I concluded that the pickling of the XML Registry (GlSpecParser class) is not sufficient since the unpickling doesn't reduce significantly the loading time. However the pickling of the API (enums and commands) reduces the loading time by a factor 5.

The CachedGlSpecParser should solve the loading time issue, and I don't have no more idea to reduce the loading time.
