Define budget segment models

• Introduce getGoverningEntityIDsForProjects utility method (#50)
• Define budget segment models (#58)
  • budgetSegment
  • budgetSegmentBreakdown
  • budgetSegmentBreakdownEntity
• Fix the method to get current and latest project versions in getAllProjectsForPlan (#60)

Expose `DISAGGREGATED_LOCATIONS` codec

Extract DISAGGREGATED_LOCATIONS codec out from DISAGGREGATED_DATA and expose it (#55)

Add ability to get current and latest versions of project plans

Extend getAllProjectsForPlan utility method to support both 'current' and 'latest' versions (#54)

Define permissions for deleting projects

• Define permissions for deleting projects (#53)
  • DELETE_ANY_PROJECT (global scope)
  • DELETE (project scope)

Reduce timestamp precision of `createdAt` and `updatedAt`

To allow for cooperation between other (legacy) models and models defined in this library, cut the precision of updatedAt and createdAt to 3, for seqeulize defined models (#51)

Define error classes and condition field related models

• Improve error messages related to model data access to make debugging easier (#36)
• Introduce findAndOrganizeObjectsByUniqueProperty fetching function that combines a database fetch with an organizeObjectsByUniqueValue call to produce a map that is annotated with the table name of the objects contained within. Utility method getRequiredData should be use to interact with this annotated map (#36):
• Expose createMany interface for creating multiple rows inside a table at once (#47)
• Define condition field related models (#48)
  • conditionField
  • conditionFieldType
  • conditionFieldReliesOn
• Define more error classes (#49)
  • BadRequestError
  • NotFoundError
  • PreconditionFailedError

Accept `null` for optional user data

When providing data to model's create method, null is now accepted for columns marked as optional (#43)

Define utility types and relax json types

• Introduce permissions to allow for plan visibility changes in PM: (#40)
  • CHANGE_ANY_PLAN_VISIBILITY_IN_PROJECTS
  • MAKE_VISIBLE_IN_PROJECTS
• Introduce EmptyTuple type and EMPTY_TUPLE codec (#39)
• Define type for projectVersionAttachment.value (#39)
• Handle planEntityVersions with null planEntityIds (#39)
• Allow for partially-defined indicator units (#39)

Define more models

• Define following models:
  • organization (#41)
  • projectContact (#42)
  • projectVersionGoverningEntity (#38)
  • projectVersionHistory (#38)
  • projectVersionOrganization (#42)
• Define getOrganizationIDsForProjects utility method (#41)

Make the package standalone, improve errors and define lots of utility and data fetching methods

• Specify @types/lodash and @types/node-fetch as regular dependencies to make this library usable by just installing in other repos (#34)
• Introduce groupObjectsByValue and organizeObjectsByUniqueValue utility functions (#32)
• Improve the errors produced when validating data by including identifiable information in the error messages, and giving more human-readable error messages to the user, which should improve debugging going forward. (#32)
• Expand/correct type definitions for columns of attachmentPrototype and attachmentVersion (#32)
• Migrate indexedObjectType from hpc_service to this repo (#32)
• Migrate JSON definitions for caseloads and attachments (#32)
• Introduce following data fetching methods that allow to get all (#33):
  • Governing entities for a plan - getAllGoverningEntitiesForPlan
  • Plan entities of a plan (which are also validated) - getAndValidateAllPlanEntities
  • Projects for a given plan - getAllProjectsForPlan
  • Attachments of a plan (with a given type) - getAllAttachments
• Define projectVersionField model (#35)
