Introduce a practical EMMO guide

[yoavnash]

How to

• add a numerical value
• add a string value
• specify measurement units
• query the attributes of CUDS object

[yoavnash]

Add a numerical value:

from osp.core.namespaces import math, metrology, my_namespace

value=5
c = my_namespace.MyClass()
real_number = math.Real(hasNumericalData=value)
c.add(real_number, rel=metrology.hasQuantityValue)

Add a string value:

from osp.core.namespaces import math, metrology, my_namespace

value='cowabunga'
c = my_namespace.MyClass()
symbol = perceptual.Symbol(hasSymbolData=value)
c.add(symbol, rel=metrology.hasQuantityValue)

@JoanaFMorgado Do you think this could fit better in the EMMO docs? (GitHub / GitLab)

Another option: add this info as a part of an EMMO use case that builds on previous tutorials and use such tutorial to better connect it with materials science.
