Add `get_GeometryPath` as a wrapper function for `getGeometryPath` in OpenSim 4.5

[cvhammond]

It seems that OpenSim 4.5 has removed get_GeometryPath() from the core library and associated MATLAB wrapper. Can you please add get_GeometryPath() as a wrapper for getGeometryPath() so as to ensure backwards compatibility for anyone who is migrating from OpenSim 4.4 to OpenSim 4.5?

Hi @cvhammond, getGeometryPath() is compatible with both OpenSim 4.4 and 4.5.

The get_ syntax is typically reserved for property methods, the unnamed property GeometryPath was removed in favor of the named property path of type AbstractGeometryPath. See the PR linked above for more details.

I added a note to the OpenSim 4.5 release notes on Confluence.

@cvhammond, thanks again for bringing this up, but since we do have the backwards compatible option we do not plan to add this wrapper for the reasons stated above.
