* adds new field 'parameter type' to PartParameterTemplate model
* Move part parameter settings onto their own page
* Add "choices" and "regex" template types
* Adds validation for PartParameter based on template type
* javascript cleanup
* Fix for serializers.py
* Add unit testing for parameter validation
* Add filters
* Rename "type" field to "param_type"
- Should have seen that one coming
* Coerce 'boolean' value to True/False
* table update
* js linting
* Add requirement for "pint" package
* Add validator for physical unit types
- Revert a previous migration which adds "parameter type" and "validator" fields
- These will get implemented later, too much scope creep for this PR
- Add unit test for validation of "units" field
* Update PartParameter model
- Add data_numeric field (will be used later)
- Add MinLengthValidator to data field
* Run validation for part parameter data
- Ensure it can be converted to internal units
* Update admin interface to display partparameter values inline for a part
* Adds validation of part parameter data value
- Also converts to base units, and stores as "numeric" value
- Display "numeric" value in tables
- Create new file conversion.py for data conversion
* Update unit tests and fix some bugs
* Update docstring
* Add units to parameter columns in parameteric part table
* Allow part list to be ordered by a particular parameter value
- Annotate queryset with new "order_by_parameter" method
- Skeleton method for future work
* Bump API version
* Adds unit testing for sorting parts by parameter value
* Update historical data migrations
- Turns out RunPython.noop is a thing?
* Cache the unit registry
- Creating the unit registry takes a significant amount of time
- Construct when first called, and then cache for subsequent hits
- Massive improvement in performance
* Throw error on empty values when converting between units
* Data migration for converting existing part parameter values
* Handle more error cases
* Show parameteric table on top-level part page too
* Unit test for data migration
* Update credits in docs
* Improved error checking
* WIP docs updates
* Fix parameteric table filtering
* remove zoom property
* Fix for import path
* Update parameter docs
* Run background task to rebuild parameters when template changes
* Make "data_numeric" field nullable
- Defaulting to zero is not appropriate, as the actual value may be zero
- Sorting still seems to work just fine
* Fixes for unit test
* More unit test fixes
* Further fixes for unit tests
