metadata

[zeyus]

move mocap metadata to inherit from timeseries metadata (for applicable vars)
time series (and inherited) will contain an ExperimentalMetadata object (trial, subject, etc)

done, see:

and also:

which allows two types of data and associated metadata

I think it's still worth adding a level-wide metadata object and attaching it to the level

then when looking up metadata it should have a hierarchical lookup process starting from the current data's metadata, then the level, then the level above etc and finding a particular key or on request combining them into one metadata set for each specific timeseries / empirical data object
