Target.description defaults to "" (empty str)
Substrate.thickness defaults to "" (empty str)
Substrate.thickness_unit is now hardcoded to "μm"
did you know? apparently h5py does NOT like null values
get_instruments returns a dictionary with the names of every system used
during the deposition
unfortunately, NeXus standard allows for a single value of all three
keys per every sample - not every layer
this means that every layer has its own data for laser, rheed system and
depo chamber which IDEALLY is the same for every layer, but in practice
they COULD be different and I still don't know how to deal with this
only lacks the instrument_used data and units of measurement
NOTE: units of measurement are hard to collect, but could be assumed
considering our instruments are standard
takes API key and elabid of the "entrypoint" sample as input
returns indented JSON with the reconstructed dataset!
currently lacks instruments_used data (matter of minutes)
and all the layer data (already present in Layer-class objects)
the fix changes "sample_data" - which was residual from copy-pasting the
call_entrypoint... function and therefore undefined - with
"material_data" which is very well defined in the previous line
* function get_entry_from_elabid moved to the top to be used by classes
* class Layers renamed Layer
* class Layer expanded and completed with all NeXus-needed metadata
* classes improved with "quality" error management
* class Material added, for now it fetches just compound_elabid and
compund chemical formula (as attribute and method respectively)
* class Material has get_compound() method which needs some commenting
* DEBUG MODE improved to cover all cases: layer, sample, substr. and pld
target; creates a new shortcut for prompting (read line 147)
* removed herobrine (fuck i'm old aren't i)
