v1.7.2

1.7.2 (01JUN17)

• updated property.part property that gets the part for its property. For model this did not work as underlying only category=INSTANCES were retrieved. Thanks to @joost.schut for finding it and reporting.
• updated requirements for development.

1.7.1 (29MAY17)

• Added Part.multiplicity property method. Use the pykechain.enums.Multiplicity to check the multiplicity of a part against the set multiplicities.
• Updated documentation (a.o. the Basic Usage notebook).

1.7.0 (29MAY17)

• Added ReferencyProperty.choices() convenience method to provide you the list of parts (instances) that are acceptable as a choice for the value of the reference property.
• Added Part.proxy_model() method that will return the model that is used as the basis for the proxied model. A proxied model is a linkedcopy of the proxy_model that can have a different name, but follow that exact model definition of the proxy_model including its properties and submodel parts. A handy way to create model structures in the catalog world and use a multiple of those in the product world. An example is provided in the documentation.

• Added the ability to customize an activity using the Activity.customize() method using a proper inspector NG json.
• Upgraded package requests to the latest version.
• Updated documentation according to PEP257.
