update diagram with individuals upflex and downflex (of type ic-data:usage)

insert upflex and downflex individuals of type ic-data:usage

upload diagram s2

- remove redundant properties
- add ic-s2:powerForecastElement
- remove incorrect domain on endTime

Removal of class virtual device and property haslimitrange (substitued by allowedlimitrange)

Conflicts:
	ontology/Interconnect/ic-data.ttl

change range and property type on ic-s2:fillRate

change property supplyrange from datatypeproperty to objectproperty

delate class ic-s2:ControlScheme, individuals of the class and property hasoptimizationscheme

insert domain and range on property supplyrange

removal of the property costvalue

removal of property demandratevalue

removal of property costcurrency

update domain on the property endTime

remove the property ic-s2:leakBehaviourDetail

fix domain on hasunitofmeasure from intersectionof to unionof

add numberRange as range of ic-s2:hasDemandRate

adding range ic-s2:NumberRange on property hascost

removal of the class ACMeasurementPhaseDifference  according to our latest conceptualization of voltage. n.b we still have the conceptualization of 'acmeasurementphasedifference' which is ic-tplg:ACMeasurementPhase. - removal of the individual of acmeasurementphasedifference according to our latest conceptualization
-removal of long series of blank nodes with restrictions (erroneously produced by protege in the script file)

change in the diagram. Alignment  with the latest conceptualization of voltage

update on the comment of ic-data:GaussianDatapoint

removal of max qualified cardinality with blank node at the bottom

removal of description of the domain of ic-tplg:hastopologicalassociation from ic-data

typo correction

change of datatypeproperties in object properties (in time ontology, interval is a class)
removal of suproperties relationships because of conflicting range domain with the superproperties

device_3 example individual removal

removal of a duplicate property (we have that conceptualization in hasoperationmode)

ic-flex ttl file in line with the latest conceptualization

-	I have internally (in the ttl file) re-defined om:hasprefix because it was giving an error.

-	I added the objectproperties includescommand and concernsdevice. They were not present in the ttl model.
-	I removed the restriction on user profile at the level of the preference. We already use the domain and range on preference.
-	I added the object property belongstouser (which was present in the diagram but not in the model).
-	I added the objectproperty hasLocation
- I put a restriction on the class preference.
