I have written a working antlr4 parser and need an expert to finish the processing of the parse tree. I need help in transforming it into a simplified abstract parse tree. The requirements of the output data structure: - can be serialized to json later on - reflects the ANTLR parse tree a 100%, also in order of appearance of the nodes - I plan to build sql queries based on the data structure later on, please come up with a design that is easily navigatable through a nested key:value like structure for example - there are intermediary nodes in the parse tree that do not contain any useful information. These nodes shall be skippable (configurable), so they don't appear in the final (simplified) abstract parse tree. Important: final/terminal values can be located below of one or more skipped nodes. They must not be lost. Examples for nodes to be skipped (example code availanle upon request): "term5","term4","term3","term2","term","factor"
