can't load NWB file from a directory outside of main matnwb directory

[cechava]

trying to read in a file from outside of matnwb file produces the following error:

>> readFile = nwbRead('test_export.nwb');
28  if any(saveDirMask)
Error using save
Cannot create 'core.mat' because 'namespaces' does not
exist.

Error in spec.saveCache (line 10)
save(cachePath, '-struct', 'NamespaceInfo');

Error in nwbRead>generateSpec (line 123)
    spec.saveCache(Namespace, saveDir);

Error in nwbRead (line 54)
        generateSpec(filename, h5info(filename,
        specLocation), 'savedir', saveDir);

I verified that the namespaces folder is in my MATLAB search path (abridged below for readability)

Probably a result from one of the recent merges since this used to work without problem.

Can't quite reproduce it but I do have a fix for nwbRead not using your core namespace directory. MatNWB usage should only require adding the root matnwb directory to path.
