/**
* Load oaobject classes into pojo structure that will allow pojo (json) to be loaded automatically into OAObjects.
* This is then used by json.OAJacksonDeserializerLoader to load POJOs to JSON to OAObjects.
*
* Note: the pojo generator for oamodels might not have pkey properties for pojo objects, so this is a way to use importMatches and link
* unique values that are defined in the model to find exact matches.
*
*
* there are three ways to match/find (ex: when deserializing) a json object with it's matching OAObject
* - Class has one or more defined pkey properties that are included in the pojo class.
*
- Class has one or more properties or linkOnes that are importMatches.
*
- A one2many link has a unique property, and a equals propertyPath for them to share a common root that make it unique.
*
*
* See OABuilder model OABuilderPojo.obx
* See PojoLoader in OABuilder for version used for code generator.
