Complete_Street_Rule_Release_2.6.4

This version of the rule is for CityEngine's 2020 Release, and has been tested in the most recent beta. Many of the changes in this release relate to the ReadMe, sample scene, animations, and rules. The main changes to the repository in the 2.6.X series are listed below, with changes specific to this release in bold.

• Object Instancing - based on feedback from users it was observed that object instancing was disrupted as are result of various old commands in the code. These commands were removed in a sizable refactor. This release includes that refactor and bug fixes that resulted from that. This enables inserted object to more readily work as replaceable object in software such as Unreal & Unity for simulation and asset replacement. In addition, material names are set in many cases to assist with asset replacement.
• Both the default scene, ReadMe, and supporting animations have been updated to emphasize the scenario oriented functionality of the rule.
• Raised Crosswalks were integrated into the rule. They don't work all the time as a result of limitations in CityEngine, but when they do they look pretty nice.
• Add Context Queries to sidewalk trees and benches to avoid curbside management features. This means trees won't appear adjacent to a curbside drop-off area for example.
• Update all annotations to their modern equivalents including specifying distances, percents, new ranges, and other edits.
• Add percent deviations to tree insertions. This means that there is some baseline variance of about 10% added to the heights of inserted vegetation. Only occurs on higher LODs.
• Miscellaneous bug fixes or edits including offsets of lamps in different locations, increased the length of parking spots in parking lanes, code simplification, transparency edits, stamp rule bug fixes, and refactor crosswalk code.
